  • What I should know about memory management?

    - by bua
    first of all: I don't use stackadmin or similar so please don't vote for moving there, I'm reading man top and paper "what every programmer should know about memory ..." I need really simple explanation like for retard ;) Having following top dump: top - 11:21:19 up 37 days, 21:16, 4 users, load average: 0.41, 0.75, 1.09 Tasks: 313 total, 5 running, 308 sleeping, 0 stopped, 0 zombie Cpu(s): 0.4%us, 0.6%sy, 0.9%ni, 96.2%id, 0.1%wa, 0.0%hi, 1.9%si, 0.0%st Mem: 132103848k total, 131916948k used, 186900k free, 54000k buffers Swap: 73400944k total, 73070884k used, 330060k free, 13931192k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3305 tudb 25 10 144m 52m 940 R 6.0 0.0 1306:09 app 3011 tudb 15 0 71528 19m 604 S 3.3 0.0 171:57.83 app 3373 tudb 25 10 209m 93m 940 S 3.0 0.1 1074:53 app 3338 tudb 25 10 144m 47m 940 R 2.7 0.0 780:48.48 app 4227 tudb 25 10 208m 99m 904 S 1.3 0.1 198:56.01 app 8506 tudb 25 10 80.7g 49g 932 S 2.0 39.6 458:31.22 app I'm wondering what is: RES (my expl. physical memory consumption ? see 49GB) VIRT (memory mapped disk to cache? see 80GB) SHR (shared pages?)

  • Proper approach to debug PC startup problems (POST)

    - by saurabhj
    My CPU was heating up to around 65 deg C and last time this had happened (about a year ago), I got thermal paste put between the CPU and heat sink and this managed to get it down to about 45 - 50 degrees. This time, I got some thermal paste and put it myself. However, my PC is not showing the POST display and not starting up. This is what happens LEDs light up HDDs spin Mouse is getting power All fans including the processor fan starts No display on monitor No diagnostic beep sounds (no sounds at all) What I have tried Removing everything including RAM, HDD, PCI cards, AGP card Boot up machine No changes from first state. What steps can I take to figure out where the problem lies? Note (might be important) When I removed the heat sink, the processor came out with it (it was stuck to it inspite of the processor latch on) Had to pry it separate with a screw-driver. Configuration Pentium 4, 2.8 Ghz with HT (very old, I know) Original Intel Mobo with onboard sound and graphics (GB series) 2x512 Mb DDR-RAM 2 SATA disks (320 Gigs / 250 gigs) DVD Writer Creative Sound Card Network card Any help would be appreciated. Thanks!

  • What is the best hosting option for Flash web-widget?

    - by par
    Our Flash web-widget has got highly popular. It is downloaded around 100,000 times per day. And that is the problem. Our server bandwidth is too narrow to deliver the widget to the clients fast. The widget is loaded very slow. Probably 20 times slower than before (at peak times). Probably I have choosen not the right hoster for my task - delivering 1 MB Flash widget to 100,000 users per day. What is the best hosting solution in my case? I'm not good at server administration so forgive me if I sound naive. The details are the following. Our hoster options: -Dedicated server, Ubuntu -10 Mbit Connection -monthly bandwidth limit: 2000 GB Widget size is 1 MB. The widget consists of the main SWF and a number of loaded SWF and data files.

  • PHP Not Automatically Updating With ?reload=1

    - by user32007
    A friend built a ranking system on his site and I am trying to host in on mine via wordpress and godaddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo ""; exit; } ob_start(); // start the output buffer ?

  • Constant crashes in windows 7 64bit when playing games

    - by yx.
    I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

  • java memory allocation under linux

    - by pstanton
    I'm running 4 java processes with the following command: java -Xmx256m -jar ... and the system has 8Gb memory under fedora 12. however it is apparently going into swap. how can that be if 4 x 256m = 1Gb ? EDIT: also, how can all 8Gb of memory be used with so little memory allocated to basically the only thing running? is it java not garbage collecting because the OS tells it it doesn't need to or what?

  • Ubuntu 12.04 VirtualBox on powerful W7 quite slow

    - by wnstnsmth
    I own a Thinkpad T420s with 8GB RAM, 160 GB SSD and a quite fast i7 processor. Summa summarum a very fast computer that works perfectly. Now, I am not very impressed by the performance of my Ubuntu 12.04 virtual machine running on VirtualBox 4.1.18. I assume that Virtual Machines are always a bit slower than the guest system, still I think it should be more performant given the hardware settings I give it: 4096 MB RAM 1 CPU without CPU limitation (I would like to give it more but then it does not seem to work - I am not experienced in this maybe somebody could give me advice on this too) Activated PAE/NX, VT-x/AMD-V and Nested Paging 96 MB Graphics Memory (no 2D or 3D acceleration) ~ 14 GB disk space, currently about 7 GB are used Maybe I misconfigured something, could you give me a hint please? Thanks! Edit: What I mean by slow is that for example switching tabs in the browser (whether FF or Chrome) only goes with a 0.5s delay or something, as well as switching application windows and/or double-clicking applications in the dock to get all open windows.. opening Aptana takes about a minute whereas opening something like Photoshop on the guest system takes 5 seconds

  • running a laptop continuously

    - by intuited
    I have an experienced laptop — a Dell Latitude D400, with a Pentium M CPU — that I'd like to run as an always-on server. This model was launched in 2004; I got mine second-hand in about 2007. I've heard that continuous operation is generally not a good idea with consumer hardware, but am lacking in specific knowledge about related problems, and have little idea of how much such usage patterns would reduce the lifespan of the machine. I'm mostly concerned with the unit's core components; parts such as the hard drive which are readily replaceable are, well, readily replaceable. What sorts of things can I do to increase the lifespan of this machine under such circumstances? For example, I'm guessing that it would be wise to limit the CPU frequency or take other steps to keep the internal temperature low. However, I'm not sure where the point of diminishing returns would lie with such an approach — 50°C? 40°C? Would it be useful to suspend the machine periodically, for perhaps an hour each day, or a few hours each week?

  • Odd one: IE6 showing the "view source" command enabled when I was expecting it to be disabled.

    - by caerphilly
    Hi, OK, I admit this problem is odd. I'm just trying to understand why IE is behaving the way it is. I realise that logic may not apply here :) I have Internet Explorer 6 (Sp1) running on Windows 2000. The IE option "Do not store encrypted pages to disk" is checked (enabled). The temporary internet files folder is empty. TEMP and TMP environment variables are set to valid folders. I'm connected to a web server over SSL. The web server is serving a page over SSL with the HTTP cache-control header set to "no-cache, no-store". I was expecting the "view source" command to be greyed out in this circumstance (as it is on another machine). But it works. When I "view source", I get an entry in the Temporary Internet Files folder with an "internet address" property of "view-source:https://myserver/...." and the content of the page. I wasn't expecting that. I can't understand why one machine is different to another in this regard. Obviously there is some environment/setup difference, but I can't track it down. Anyone have any bright ideas?

  • Performance-optimizing Oracle 10g on a server that is also a Tomcat JSP app server?

    - by PKHunter
    I have inherited a simple RedHat 5 - 64bit platform. It has SCSI disks on RAID1, with 16GB of RAM. Double Core CPU. Oracle 10g, Release 2. This would be a decent platform for running the DB only, perhaps, but the same server in an "A-A mode" clustering (very simple) also runs Tomcat and there are several Java servlets running on this. Sadly there is no caching platform etc. We only use an external CDN for some html caching. I am personally more familiar with web environments on the LAMPP platform (apache, php, mysql, postgresql). PROBLEM: Because the server has both Tomcat JSP/Java and Oracle 10g running on the same server, with no caching, I have some issues of the server going down. Often, sadly. QUESTION: What are my options in terms of improving performance of all these different apps? Connection Pooling? Example, in Postgresql world we have PgBouncer, which really helps things. Does Oracle have something similar? Or is there a famous Java-based external pooler that people use in production environments? (I'm not familiar with Java) Any "SQL cache" as in the MySQL and Postgresql world? Any other kind of application cache, as "APC" or "eAccelarator" in the PHP world? The "OSCache" stuff from the Java world (JSP thingie I found on Google: http://onjava.com/pub/a/onjava/2005/01/05/jspcache.html?page=2) ... What else? Sorry if this is a noob question. I have googled and googled, but problem is I don't know what to google for, other than the broad general concepts above. So if not full answers, I would even appreciate basic pointers and I am happy to JFGI myself. Thanks!

  • Ubuntu's garbage collection cron job for PHP sessions takes 25 minutes to run, why?

    - by Lamah
    Ubuntu has a cron job set up which looks for and deletes old PHP sessions: # Look for and purge old sessions every 30 minutes 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] \ && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 \ -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir \ fuser -s {} 2> /dev/null \; -delete My problem is that this process is taking a very long time to run, with lots of disk IO. Here's my CPU usage graph: The cleanup running is represented by the teal spikes. At the beginning of the period, PHP's cleanup jobs were scheduled at the default 09 and 39 minutes times. At 15:00 I removed the 39 minute time from cron, so a cleanup job twice the size runs half as often (you can see the peaks get twice as wide and half as frequent). Here are the corresponding graphs for IO time: And disk operations: At the peak where there were about 14,000 sessions active, the cleanup can be seen to run for a full 25 minutes, apparently using 100% of one core of the CPU and what seems to be 100% of the disk IO for the entire period. Why is it so resource intensive? An ls of the session directory /var/lib/php5 takes just a fraction of a second. So why does it take a full 25 minutes to trim old sessions? Is there anything I can do to speed this up? The filesystem for this device is currently ext4, running on Ubuntu Precise 12.04 64-bit. EDIT: I suspect that the load is due to the unusual process "fuser" (since I expect a simple rm to be a damn sight faster than the performance I'm seeing). I'm going to remove the use of fuser and see what happens.

  • Microsoft Word 2008 on the Mac sometimes "Disappears" documents, really.

    - by Ross Charette
    This happens in a computer lab environment, has happened at least 3 times. We are running Microsoft Office 2008 for mac on Leopard, everything is updated. Our user's home directories are on a network drive, but the /Library/Cache folder is running locally. Typically a student will have a Word file that they have been working on, it's been saved before they even logged onto the computer that day. They log on, open the document, click the save icon (not go to File Save), sometimes even save multiple times, then close Word. The document is now gone. It's not hidden, there are no autosaves or anything in the Cache folder. Definitely not in the trash or trashes folder. It can't find it when you click on it in 'recent documents'. Searching meticulously though every folder in their home drive turns up nothing. They look using Finder, I look ssh'd as root into their home using ls -la. I look for similar files in case they renamed it by mistake. It's gone. Disappeared. Vaporized. It's happened to at least 3 different users in the past year. Much whining. Any idea?

  • Fedora Core 6 Migration

    - by Matthew Sprankle
    I am at a loss as to what I should to for this server. I need it to run php5.3 and corresponding version of mysql. I received a client today through work that is using Fedora core 6 running 10 very small websites on some very hodge podge setup. My original idea was just upgrade to php5.3. I have yum (installed 3.0.8) reconfigured for the fedora archive. The latest version of php it allows is 5.1.8. I am still relatively new to server setups and am nervous about wiping their server to upgrade it. Since it is about 6-8 years old I'm not sure if it will even support the newest version of fedora. The server specs are: Parallels Plesk Panel version 9.5.4 Operating system Linux 2.6.9-023stab048.4-smp CPU GenuineIntel, Intel(R) Xeon(R)CPU E5335 @ 2.00GHz (10gb disk space and 1gb of memory). I use fedora for my personal server so I was a little familiar with it. I haven't done anything too extravagant. Is there a way I can escape this nightmare with installing php5.3 or do I need to migrate these sites to a new server?

  • Can a VM perform better when only two cores instead of four cores are presented to it?

    - by arcain
    We had a VMWare VM at work with two cores allocated to it that ran a pretty heinous process in IIS. Under load the process was maxing out the CPU usage on both cores, so we asked our system engineers to present the other two cores of the physical processor to the VM. The engineer immediately said that this would not improve performance at all, but would make the VM perform worse. That statement didn't make much sense to me, and I'm wondering how what the engineer said could be true. Are there actually cases where four cores presented to a VM would cause worse performance than two cores on the same physical hardware? Let's assume an ideal situation where there's only one VM on the host server, so nothing is being shared with other OS instances. I believe the physical server had a single quad core processor, and was most likely hosting multiple VMs. I don't really know what version of ESX was running on the host, nor do I know with certainty what the physical processor config was, but from within the VM I had access to, I saw two 3.33 GHz AMD processors. In the end, I never got to test the engineer's assertion out because (while we were trying to get the VM upgraded) we were able to optimize the process and reduce it's CPU consumption, and 2) we ended up migrating to a different VM on another ESX server which had four cores presented to it.

  • Server specification recommendation

    - by foo
    To cut the story short, I can't buy an item (server/cpu/motherboard/ram) that costs more than USD 330. However, I can combine them, meaning, I can buy a CPU that costs USD 330 and motherboard that costs USD 330. With this limitation, I can't buy a powerful 1U server which will definitely costs me more USD 330. With that in mind, I was hoping to build a powerful desktop PC which will be used as a database server. However, through my experience, desktop PC doesn't last very long, usually the motherboard will just die by itself after 1 or 2 years. So, what would you guys recommend me to buy with this kind of budget? Every item must be <= USD 330. Will be used as a MySQL server. RAID would be nice. 1TB is pretty big for my data. I do not need external graphic card (onboard would do just fine), mouse, keyboard, monitor. Linux friendly. One ethernet port is good enough. It's important that those hardware is made of components that will last long (at least 3 years or something). The server will be placed in an air conditioned room, but a good ventilation for the server is always preferred. I won't overclock it. Intel processor is preferred. Thanks in advance.

  • Apache mod_disk_cache on a seperate drive

    - by pavs
    how can I set Apache mod_disk_cache on a separate drive from where the OS/Apache is installed? I have set up this on my apache2.conf: <IfModule mod_cache_disk.c> # cache cleaning is done by htcacheclean, which can be configured in # /etc/default/apache2 # # For further information, see the comments in that file, # /usr/share/doc/apache2/README.Debian, and the htcacheclean(8) # man page. # This path must be the same as the one in /etc/default/apache2 CacheRoot /media/cacheHD # This will also cache local documents. It usually makes more sense to # put this into the configuration for just one virtual host. CacheEnable disk / # The result of CacheDirLevels * CacheDirLength must not be higher than # 20. Moreover, pay attention on file system limits. Some file systems # do not support more than a certain number of inodes and # subdirectories (e.g. 32000 for ext3) CacheDirLevels 2 CacheDirLength 1 </IfModule> and it doesn't seem to be caching anything at all. The drive itself is a freshly installed ssd drive formatted with ext4.

  • Java games applet not connecting to Yahoo

    - by Steve
    Hi. I am trying to play a Y! game which use a java applet. The applet displays the message: Alert. Unable to connect to server. One of four things could have caused this: 1) You are behind a firewall. 2) You are not connected to the internet. 3) The games server is down. 4) You have a stale page in your cache. I have added an exception to the Windows firewall for java.exe. I am obviously connected to the Internet okay. The games server is not down when I am at home. I doubt it is down when I am at work. I have never successfully loaded this page before, so I doubt I have a stale page in cache. Could it be the corporate firewall? Nothing else in my web browser has been blocked before. Maybe the java applet connects on a different port to the browser. What should I test?

  • Escaping %’s in file-/folder-names at the command-line

    - by Synetech
    Does anybody of a way to access files and directories that have a % in their name (which is valid) from the command-line? Specifically, if there are two %’s and the text between them happens to correspond to an environment variable. For example, if there is a file called C:\blah\%temp%.txt or a folder called C:\Program Files\%temp%\, none of the following will work because the variable gets expanded: > dir "c:\blah\%temp%.txt" > dir "c:\blah\^%temp^%.txt" > dir "c:\blah\%%temp%%.txt" > dir "c:\blah\\%temp\%.txt" > dir "c:\program files\%temp%" > dir "c:\program files\^%temp^%" > dir "c:\program files\%%temp%%" > dir "c:\program files\\%temp\%" Using wildcards will work, but does not uniquely select the file/folder and may include others: > dir "c:\blah\?temp?.txt"        (also shows ztempz.temp, 1tempa.txt, etc.) > dir "c:\program files\?temp?"   (likewise) (This is frustrating because every now and then—usually when Explorer is restarted for whatever reason—the environment variables stop expanding and some places where they are used end up creating files or directories with the environment variable in it. For example, because I configured Chromium to store its cache in a subdirectory of %temp%, if the variable expands, it is fine, but when it doesn’t, Chromium creates a directory called %temp% under its own directory and stores the cache—which can get large—there. I want to add a line to my temp-/junk-file cleaning script to automatically delete that folder if it exists, but I cannot figure out how to access it from the command-line without resorting to wildcards.)

  • How many VPS do I need for my website? [duplicate]

    - by michael
    This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers I made a website which aims at simulating a trading market. There are a list of prices and corresponding volumes that people want to purchase. Users can purchase at any price any time. My website retrieves the prices and volumes from my database every 2 seconds (I have to update the user's browser frequently to allow them to see the current market). Users' database INSERT query can be sent any time if they purchase. I used ajax to post or get data from my database (sometimes nested ajax calls). So, every 2 seconds, each user will send or retrieve data by using more than 20 database queries (in order to show a users the current prices and volumes). Also, I may have 200 users at a time. I was not using VPS before, and I got banned because of using too much CPU resources on my host. Now, I've purchased VPS*2 from a hosting servers. I have: CPU Speed: 2000 Mhz Memory: 2048 MB Disk Space: 20000 MB Bandwidth: 2000 GB Connection: 40 Mb/s Dedicated IP's 2 IP's Is this enough for my 200 users? Also, which VPS OS is suitable for me? Thank you.

  • What is the fastest cyclic synchronization in Java (ExecutorService vs. CyclicBarrier vs. X)?

    - by Alex Dunlop
    Which Java synchronization construct is likely to provide the best performance for a concurrent, iterative processing scenario with a fixed number of threads like the one outlined below? After experimenting on my own for a while (using ExecutorService and CyclicBarrier) and being somewhat surprised by the results, I would be grateful for some expert advice and maybe some new ideas. Existing questions here do not seem to focus primarily on performance, hence this new one. Thanks in advance! The core of the app is a simple iterative data processing algorithm, parallelized to the spread the computational load across 8 cores on a Mac Pro, running OS X 10.6 and Java 1.6.0_07. The data to be processed is split into 8 blocks and each block is fed to a Runnable to be executed by one of a fixed number of threads. Parallelizing the algorithm was fairly straightforward, and it functionally works as desired, but its performance is not yet what I think it could be. The app seems to spend a lot of time in system calls synchronizing, so after some profiling I wonder whether I selected the most appropriate synchronization mechanism(s). A key requirement of the algorithm is that it needs to proceed in stages, so the threads need to sync up at the end of each stage. The main thread prepares the work (very low overhead), passes it to the threads, lets them work on it, then proceeds when all threads are done, rearranges the work (again very low overhead) and repeats the cycle. The machine is dedicated to this task, Garbage Collection is minimized by using per-thread pools of pre-allocated items, and the number of threads can be fixed (no incoming requests or the like, just one thread per CPU core). V1 - ExecutorService My first implementation used an ExecutorService with 8 worker threads. The program creates 8 tasks holding the work and then lets them work on it, roughly like this: // create one thread per CPU executorService = Executors.newFixedThreadPool( 8 ); ... // now process data in cycles while( ...) { // package data into 8 work items ... // create one Callable task per work item ... // submit the Callables to the worker threads executorService.invokeAll( taskList ); } This works well functionally (it does what it should), and for very large work items indeed all 8 CPUs become highly loaded, as much as the processing algorithm would be expected to allow (some work items will finish faster than others, then idle). However, as the work items become smaller (and this is not really under the program's control), the user CPU load shrinks dramatically: blocksize | system | user | cycles/sec 256k 1.8% 85% 1.30 64k 2.5% 77% 5.6 16k 4% 64% 22.5 4096 8% 56% 86 1024 13% 38% 227 256 17% 19% 420 64 19% 17% 948 16 19% 13% 1626 Legend: - block size = size of the work item (= computational steps) - system = system load, as shown in OS X Activity Monitor (red bar) - user = user load, as shown in OS X Activity Monitor (green bar) - cycles/sec = iterations through the main while loop, more is better The primary area of concern here is the high percentage of time spent in the system, which appears to be driven by thread synchronization calls. As expected, for smaller work items, ExecutorService.invokeAll() will require relatively more effort to sync up the threads versus the amount of work being performed in each thread. But since ExecutorService is more generic than it would need to be for this use case (it can queue tasks for threads if there are more tasks than cores), I though maybe there would be a leaner synchronization construct. V2 - CyclicBarrier The next implementation used a CyclicBarrier to sync up the threads before receiving work and after completing it, roughly as follows: main() { // create the barrier barrier = new CyclicBarrier( 8 + 1 ); // create Runable for thread, tell it about the barrier Runnable task = new WorkerThreadRunnable( barrier ); // start the threads for( int i = 0; i < 8; i++ ) { // create one thread per core new Thread( task ).start(); } while( ... ) { // tell threads about the work ... // N threads + this will call await(), then system proceeds barrier.await(); // ... now worker threads work on the work... // wait for worker threads to finish barrier.await(); } } class WorkerThreadRunnable implements Runnable { CyclicBarrier barrier; WorkerThreadRunnable( CyclicBarrier barrier ) { this.barrier = barrier; } public void run() { while( true ) { // wait for work barrier.await(); // do the work ... // wait for everyone else to finish barrier.await(); } } } Again, this works well functionally (it does what it should), and for very large work items indeed all 8 CPUs become highly loaded, as before. However, as the work items become smaller, the load still shrinks dramatically: blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.7% 78% 6.1 16k 5.5% 52% 25 4096 9% 29% 64 1024 11% 15% 117 256 12% 8% 169 64 12% 6.5% 285 16 12% 6% 377 For large work items, synchronization is negligible and the performance is identical to V1. But unexpectedly, the results of the (highly specialized) CyclicBarrier seem MUCH WORSE than those for the (generic) ExecutorService: throughput (cycles/sec) is only about 1/4th of V1. A preliminary conclusion would be that even though this seems to be the advertised ideal use case for CyclicBarrier, it performs much worse than the generic ExecutorService. V3 - Wait/Notify + CyclicBarrier It seemed worth a try to replace the first cyclic barrier await() with a simple wait/notify mechanism: main() { // create the barrier // create Runable for thread, tell it about the barrier // start the threads while( ... ) { // tell threads about the work // for each: workerThreadRunnable.setWorkItem( ... ); // ... now worker threads work on the work... // wait for worker threads to finish barrier.await(); } } class WorkerThreadRunnable implements Runnable { CyclicBarrier barrier; @NotNull volatile private Callable<Integer> workItem; WorkerThreadRunnable( CyclicBarrier barrier ) { this.barrier = barrier; this.workItem = NO_WORK; } final protected void setWorkItem( @NotNull final Callable<Integer> callable ) { synchronized( this ) { workItem = callable; notify(); } } public void run() { while( true ) { // wait for work while( true ) { synchronized( this ) { if( workItem != NO_WORK ) break; try { wait(); } catch( InterruptedException e ) { e.printStackTrace(); } } } // do the work ... // wait for everyone else to finish barrier.await(); } } } Again, this works well functionally (it does what it should). blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.4% 80% 6.3 16k 4.6% 60% 30.1 4096 8.6% 41% 98.5 1024 12% 23% 202 256 14% 11.6% 299 64 14% 10.0% 518 16 14.8% 8.7% 679 The throughput for small work items is still much worse than that of the ExecutorService, but about 2x that of the CyclicBarrier. Eliminating one CyclicBarrier eliminates half of the gap. V4 - Busy wait instead of wait/notify Since this app is the primary one running on the system and the cores idle anyway if they're not busy with a work item, why not try a busy wait for work items in each thread, even if that spins the CPU needlessly. The worker thread code changes as follows: class WorkerThreadRunnable implements Runnable { // as before final protected void setWorkItem( @NotNull final Callable<Integer> callable ) { workItem = callable; } public void run() { while( true ) { // busy-wait for work while( true ) { if( workItem != NO_WORK ) break; } // do the work ... // wait for everyone else to finish barrier.await(); } } } Also works well functionally (it does what it should). blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.2% 81% 6.3 16k 4.2% 62% 33 4096 7.5% 40% 107 1024 10.4% 23% 210 256 12.0% 12.0% 310 64 11.9% 10.2% 550 16 12.2% 8.6% 741 For small work items, this increases throughput by a further 10% over the CyclicBarrier + wait/notify variant, which is not insignificant. But it is still much lower-throughput than V1 with the ExecutorService. V5 - ? So what is the best synchronization mechanism for such a (presumably not uncommon) problem? I am weary of writing my own sync mechanism to completely replace ExecutorService (assuming that it is too generic and there has to be something that can still be taken out to make it more efficient). It is not my area of expertise and I'm concerned that I'd spend a lot of time debugging it (since I'm not even sure my wait/notify and busy wait variants are correct) for uncertain gain. Any advice would be greatly appreciated.

  • Optimizing apache server load

    - by Jevgeni Smirnov
    We have an issue with a dedicated server load. We have 16 processors with 4 core @ 2.40GHz, if I understood correctly cat /proc/cpuinfo output. Unfortunately, I don't have access to free -m or vmstat. But from top I got that we have 24 GB. And snapshot from top about processes: As far as I see, memory is not used at all. But the cpu is used heavily. Apache consumes most of CPU.
