• Upgrading from SQL2000 database to SQL Express 2008 R2

  - by itwb

  Hi, We have a web application which uses a MSSQL 2000 backend database. We are currently paying a ridiculous amount for Shared Hosting, with the database costs alone costing us $150 per month (MSSQL 100mb extra space is $40 per month). Our database size is 896.38 MB I am looking at getting a Virtual Private Server and upgrading the database to a MSSQL2008 Express database. I am aware that the Express version is limited to a 10GB database (with R2), and is constrained to a single CPU. I have also been offered SQL Server 2008 Web Edition for $19/per month, but I cannot find many details on the difference between Express and Web. Any suggestions here? What I would also like to know is: If we upgrade the database to MSSQL 2008 database, is there any issues with possible data transformations in the future? I.e. Is it possible to download and mount it with SQL Server 2008 Standard edition? I'm more concerned about how to get data in and out of the database through SQL Management tools. Are there any other issues that I might face? Thanks, Mike

• 613 threads limit on debian

  - by Joel

  When running this program thread-limit.c on my dedicated debian server, the output says that my system can't create more than around 600 threads. I need to create more threads, and fix my system misconfiguration. Here are a few informations about my dedicated server: de801:/# uname -a Linux de801.ispfr.net 2.6.18-028stab085.5 #1 SMP Thu Apr 14 15:06:33 MSD 2011 x86_64 GNU/Linux de801:/# java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode) de801:/# ldd $(which java) linux-vdso.so.1 => (0x00007fffbc3fd000) libpthread.so.0 => /lib/libpthread.so.0 (0x00002af013225000) libjli.so => /usr/lib/jvm/java-6-sun-1.6.0.26/jre/bin/../lib/amd64/jli/libjli.so (0x00002af013441000) libdl.so.2 => /lib/libdl.so.2 (0x00002af01354b000) libc.so.6 => /lib/libc.so.6 (0x00002af013750000) /lib64/ld-linux-x86-64.so.2 (0x00002af013008000) de801:/# cat /proc/sys/kernel/threads-max 1589248 de801:/# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 794624 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 10240 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 128 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Here is the output of the C program de801:/test# ./thread-limit Creating threads ...

• What can I do to lower bandwidth cost on a bandwidth heavy site?

  - by acidzombie24

  The easiest answer is CDN but I'd like to ask. A friend of mine has a server that is used for mirror downloads. He says he is doing about 10TB of bandwidth a month which shocked me (I wonder if he is lying). I seen his site and he has no ads. I suspect he might close his website once he gets the bill. Anyways I was wondering since his CPU/RAM is not being used and his HD usage is around 15gb what he can do to lower cost if he continues this site. I said put up ads but I don't know if ads would cover it I found one CDN which offers $0.070 / GB. 10240gb (10TB) * .07 = $717 a month. That seems a little steep but he is using lots of traffic due to it being a mirror site. Also using a CDN doesnt make sense as he doesn't need multiple servers hosting the files in different areas (which is one reason he isn't using that now). He just needs a big upload pipe Is there something he can do? At the moment he is paying $200 a month on a dedicated server and he is using WAY more bandwidth then he should be using. Side question: Can gz-ing files large already compressed files help? like on (zip, rars, etc)

• Dell PE2950 - slow IO rates for writing and reading locally

  - by OrenM

  I'm having a serious issue with dell server PE2950. The server has really slow IO rates, so slow that I'm not able to use it anymore I tried few things to solve this: changing disks to new disks (configured them as raid1) changing perc card + perc cables reinstalling the OS of course, had to cause of changing of disks, centos 5.5 x64bit firmware update to everything virtual disks policy: No Read Ahead,Write Back, disk cache policy disabled. openmanage doesn't alert about anything, also i ran dell's diag tests, everything passed, also dell didn't see anything in deset log. dell offered to reseat everything, including the cpu, we did that as well, still io rates are slow I have several PE2950 servers, and I never had such a thing with any of those. All have similar or exact hardware as this one, all configured the same, with the same os centos 5.5 x64, same disks, same raid, same policy. Just for comparison: the problematic PE2950 server: [root@bad ~]# time sh -c "dd if=/dev/zero of=/tmp/ddfile bs=8k count=200000 && sync" 200000+0 records in 200000+0 records out 1638400000 bytes (1.6 GB) copied, 27.7946 seconds, 58.9 MB/s real 0m33.968s user 0m0.531s sys 0m26.000s good PE2950 server (with the exact same hardware): [root@good ~]# time sh -c "dd if=/dev/zero of=/tmp/ddfile bs=8k count=200000 && sync" 200000+0 records in 200000+0 records out 1638400000 bytes (1.6 GB) copied, 3.19999 seconds, 512 MB/s real 0m7.694s user 0m0.053s sys 0m4.057s Hopefully you will have an idea what can cause the problem.

• 4.00gb (3.25gb usable) in Windows 7 x64

  - by dotnetdev

  Hi, I have setup Windows 7 Ultimate x64 on my PC. I have 4gb RAM and my BIOS states the correct amount (4096mb), but I cannot Windows (System Manager) says I have 4.00gb (3.25gb usable). This seems to be a popular issue, and I have looked for an integrated video card (integrated with my chipset) to disable but haven't found anything. What else can be preventing me from seeing all 4gb? When I had Vista 32bit, it would say 3.25gb RAM not 4.00gb (3.25gb usable). I have an x64 CPU and when I brought my RAM, I used a compatibility tool from Crucial (the memory vendor) to test how much memory my PC can support and 4gb was the answer (this was a windows app I think). Chipset is Intel(R) G33/G31/P35/P31 Express Chipset PCI Express In the bios, I looked for an onboard video card (integrated) and there was no such thing, but a couple of other onboard devices. There are also no "Resource Mappings" settings. FURHTER DETAILS: Chipset North Bridge: Intel Bearlake G33 South Bridge: Intel 82801IR ICH9R Maximum Memory Amount 8 GB Graphics Controller Type Intel GMA 3100 (Enabled) I guess the first thing is, how do I disable the graphics controller? EDIT: This thread (http://forums.legitreviews.com/about23417.html) indicates the issue is with memory mapped devices, but someone on this thread says that does not apply to x64. The rest of the comments points to a mobo issue for the guy who started that thread. Thanks

• PHP + MYSQL site perfomance

  - by Diego

  I have to manage a site which wasn't developed by me. It is in PHP using a mysql database, which is located in the web server. The site, sometimes (when the visitors increase too much) stops responding, or respond too slow. I have developed some sites in PHP but never took care of the management so really don't know where to start. The server (the hard) seems to be fine, when the web stops responding the cpu is being used at about 55% and has a lot of memory. I'm not asking someone to solve this issue. I only would really like if someone could give me a few tips about where can I find logs and how should I read and interpret them. So, that way I would be able to know if its the net traffic, the database (which queries), or what. Thanks! Update: Forgot to say: it is a Windows Server 2003. Note: I've recorded about a day with Jet Profiler. I don't really understand all the information it provides but there is one query which it marks as really slow. It makes sense because it is a select with a where clause which has three like condition. Initially I didn't include this in my question because when I run the query from MySQL Query Browser it doesn't take any long. It is under 0.01 seconds.

• How to install QEMU on Damn Small Linux?

  - by user2934303

  i'm trying to install QEMU on a Damn Small Linux installation in order to emulate pentium features in a 486 computer. Though DSL was descontinued, it's the only linux that runs reasonably on the 486 processor, most recent kernels doesn't even boot on 486 architecture. I tried Tiny Core Linux, but it doesn't work in 486, so i seem to have no escape here. The most recent image of DSL is from 2008, it uses kernel 2.4.x, and i couldn't find a way to compile QEMU on it. Firstly, it lacks several compile tools needed for compiling it, and, it have several dependency problems. I tried some pre-compiled packages, but the only one that worked was a QEMU 5.2 RPM package (it didn't had dependency problems), and it was way too old, it wasn't capable of running windows yet, it just gave me the option of emulating a code, not a full OS as windows, and it also didn't give me the option to choose which architecture i wanted it to emulate (-cpu option). Can anyone help me with this? Also, if someone can think of some alternative to it, i'd be grateful. Thanks.

• Amazon EC2 instance was not available for few minutes (amazon showed that everything ok)

  - by Salvador Dali

  Few minutes ago my amazon Ec2 instance was unavailable for a few minutes. During this time neither I was able to connect to web-site with http, nor I was able to ssh to it. Also I was not able to connect to my amazon management console for some time (less than amount of unavailability of my instance). When I was able to connect to management console, it was showing me that everything is running smoothly (but I still was not able to connect to instance in any way for a minute or two). During this time I have checked their status page just to see that there is no issues (my instance is in Ireland and there is nothing wrong there today). After that I was able to log in. I checked my logins with last to see that no one except me was logging in. I also looked in apache logs and there was no errors or warnings during this time. Right now when I see my amazon monitor, I see a small spike in CPU in last 15 minutes (but this is from 10% to like 20%) I have no idea what can it be (I have never experienced anything like this before) and therefore I have no idea how scared should I be or what else should I look for. Can anyone give me a hint what my actions should be in such situation?

• New Windows Server 2008 R2 WIMP running slower than Windows Server 2003

  - by starshine531

  We recently upgraded a WIMP server from Windows Server 2003 (32 bit) to Windows Server 2008 R2 (64 bit). The new server has significantly better hardware than the old server, yet many processes take much longer than the old box. We have a rather complex web application process that normally takes about 7 seconds on the old box, but on the new one it takes 11-12 seconds. That's down from 15.5 seconds it took before I disabled IPV6. This process involves some queries (some of them involve transactions with maybe 3 queries between the start and commit) and creating and emailing some pdfs. Windows updates are current with a more or less fresh machine. This happens consistently even when we have almost no traffic on the site and memory and cpu aren't being hard pressed at all. The only differences between the servers other than the OS and hardware: 1) When available, we used 64 bit versions of programs 2) The new server uses MySQL 5.5 rather than MySQL 5.1 (I did run the mysql_upgrade program and we use InnoDB for the engine) 3) The new server uses PHP Version 5.3.18 rather than PHP Version 5.3.1 4) With the new OS came IIS7 rather than IIS6 of course. What could be causing better hardware to run so much slower? Let me know if you need more details. Thank you.

• Poor Write Performance in VM inside Proxmox PVE 2.0

• TeamCity sends inadequate responses after Selenium tests

  - by Dmitriy Sukharev

  I have a TeamCity 7.0.2 at CentOS 6.2 server without X Server. I've installed x11-fonts*, xvfb, firefox, xauth, extracted env. variable DISPLAY=localhost:1, and started xvfb. After that I could start Selenium tests using maven. Tests are executed, but there's an issue with TeamCity. Usually TeamCity starts hehaves absolutely inadequate (it confuses images at the page, sends xml or strange text ampersants and numbers in responses and is a bit slower), also tests are executed 4 times slower (1h 15m) at server than at tester Windows 7-based machine (25m). It worth to notice that tests launch two Jetty servers for tested application (one for REST-services application and another for client). In TeamCity I set JVM command line parameters: -Xms256m -Xmx1224m -XX:MaxPermSize=320m, and Additional Maven command line parameters ends with "-DMAVEN_OPTS=-Xmx1024m" (without quotes). Also both web-services and TeamCity uses the same Oracle server (but different Oracle users). Finally TeamCity and its build agent is at the same server. Server has only 4GB of RAM, but during testing there're 400MB of RAM and 1.2GB of swap. TeamCity and Firefox uses about 65% of CPU during testing. There's no firefox process after end of testing. My knowledge about Selenium is weak. I only know that we use 2.20.0 version of selenium-java maven dependency. Please help me to determine why TeamCity sends wrong responces after Selenium tests. I've tried to give you all information I have, but feel free to ask me for more information.

• How to stop DW20.exe running on Win 2003 Server

  - by Laurence

  Periodically my ASP.NET application crashes (usually because memory consumption exceeds maximum allowed by application pool) and DW20.exe starts up. This is a big problem because it uses huge amounts of memory and CPU for minutes at a time. I want to know how to stop DW20.exe from running. Please note, I have already tried these often mentioned solutions: Disabling error reporting in Control Panel System Advanced Error Reporting Disabling the Error Reporting Service Modifying the registry as in http://support.microsoft.com/kb/841477 (however I might have done this wrong - this doc says "add a DWReportee value of 1" - what I did was add a DWORD entry with hexadecimal value of 1 - is this right? Also only 2 of the 4 keys were present, so I only modified these, e.g. there was no HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\PCHealth key at all) So, zero points for suggesting any of the above (unless you can see I have modified the registry incorrectly)! Also zero points for suggesting I resolve whatever is causing the application crashes :) - I am figuring this out, I just want something in the mean time to stop DW20.exe eating up all the server resources. By the way, this is a Windows 2003 SP1 server, with IIS 6 and SQL 2005 installed. There is no MS Office.

• Why is windows 7 rejecting my key?

  - by acidzombie24

  I'm extremely confused. I have a genuine key and CD (I can take photos) and I am trying to install windows on my new tower. I believe this would be the 3rd PC i installed it (old, laptop now new tower). However i did change the HDD once but i doubt windows would think its a different computer bc of that. After going through phone activation it said i installed it on to many pcs..... i'm extremely confused. I'll be happy to deactivate it off my old tower if i knew how. I already grabbed all the files off of it. I tried to look up the amount of boxes i can install windows home premium on and found this http://en.wikipedia.org/wiki/Windows_7_editions What stuck out was this Maximum physical CPUs supported[40] 1 1 1 2 2 2 My new tower has 4cores (its the intel i7) but has two threads each so it sees 8. Does that have anything to do with this? But apparently ultimate supports '2'. I'm sure windows support more than 2 cpus so... what gives? Actually its physically one CPU so i guess the number of cores doesn't matter? Why is windows 7 rejecting my key?

• Laptop recommendation - Portable Gaming

  - by ivan

  So, I'm looking for a new laptop (http://superuser.com/questions/116869/toshiba-satellite-u500-totally-damaged-lcd). My requirements for a new Laptop are: -good keyboard(illuminated) and touchpad (multi-media keys included, should be better than toshiba u500) -good graphics card, with system rating of 6.3 and up for gaming graphics (my Toshiba U500 has 6.3). I used to run some heavy games on my Toshiba U500 with ATI Mobility Radeon 4570 with 512 mb VRAM but the framerates are not that nice on high settings. -Decent CPU but I think all new Core i3, i5, i7 can run most of recent resource intensive games (My Toshiba U500 has a Core 2 Duo T6500, 2.13 Ghz) I'm also looking for a long-term reliability, good sound quality, lots of fast RAM of-course(4GB DDR3 - 1066Mhz and up) and a clear looking LED screen with a decent resolution. (I can accomodate a laptop with screen size of 13-inch upto 15.6 inch, and I don't want it to be heavy because I might be taking it outdoors) I'm actually impressed when I saw HP Pavilion DV6t but the screen resolution seems to be a little too small for 15.6 inch. The Pavilion DV3 are also good but I want to know if there other options. Looking for some opinions.. Thanks. :D

• weird POST request in IIS logs

  - by MIrrorMirror

  I noticed weird log entries (unless there's something i don't understand) in my IIS (7.5) logs. it's an online dictionary with requests ( user friendly url rewriting ) and most of them are GET. However I noticed weird POST requests which are taking place by a person who is trying to crawl our content ( tens of thousands of such requests ) 2013-11-09 20:39:27 GET /dict/mylang/word1 - y.y.y.y Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) - 200 296 2013-11-09 20:39:29 GET /dict/mylang/word2 - z.z.z.z Mozilla/5.0+(iPhone;+CPU+iPhone+OS+6_0+like+Mac+OS+X)+AppleWebKit/536.26+(KHTML,+like+Gecko)+Version/6.0+Mobile/10A5376e+Safari/8536.25+(compatible;+Googlebot-Mobile/2.1;++http://www.google.com/bot.html) - 200 468 2013-11-09 20:39:29 POST /dict/mylang/word3 - x.x.x.x - - 200 2593 The two first requests are legal. Now for the third request, I don't think I have allowed cross domain POST. if that what the third log line means. all those POST requests take that much time for unknown reasons to me. I would like to know how are those POST requests possible and how can I stop them. p.s. I have masked the IPs on purpose. any help would be appreciated! thank you in advance.

• What configuration changes can I make to speed up extremely slow Windows VM's in ESXi 4.0.

  - by Shawn Anderson

  I've recently moved from VMWare Server to ESXi 4.0. Running on Dell T310. My VM's have been restored but they are running dog slow compared to VMWare Server. I loaded ESXi 4.0 using only default values. Where are some areas where I can tweak the performance? Even logging onto the VM's can be extremely sluggish. Trying to install software on any of them is a new experience in pain. Dell PowerEdge T310 Xeon X3460 2.80 GHz 32 GB RAM 1 HD (2 TB) I have 16 VM's on this server, but only six or so will be running during my testing. I keep an eye on the Resource Allocation and Performance tabs for the host and I never see CPU or RAM getting anywhere close to pegged. Events tab does show some notices for video RAM issues and some hints on Windows activation issues, but nothing that would point to the sort of sluggishness that I'm experiencing. 1 Windows Server 2008 R2 (64-bit) - 4 GB RAM 1 Windows 7 (32-bit) - 2 GB RAM 1 Vista (32-bit) - 1 GB RAM 3 XP (32-bit) - 1 GB RAM Over to you! Thanks - Shawn

• PHP scripts randomly becoming really slow to respond - Database lockup?

  - by webnoob

  Hi All, I wasn't sure whether to post this here or on stackoverflow, so apologies if its in the wrong place. I have about 7 php scripts running on a centOS VPS. Each of these scripts contacts a game server and processes the logs, with the logs it either does some database queries or sends info back to the game server. I am having an issue where some of the scripts will randomly become REALLY slow to respond and I don't know where to start with my debugging. Each script connects to its own database schema but on the same MySQL server. Each script will do about 4 inserts per second and twice as many select statements on their respective databases. I thought a database lockup may cause the issue but some console messages that are read from the database are sent to the game servers console without issue every 30 seconds, even when the script is slow to responding to other commands. Non of the scripts are using a lot of memory or CPU power. About 0.1% each. I know this information is really vague but I don't know linux very well at all (in fact, top is about my limit) and I really don't know where to start debugging this. Thanks.

• 1GB cached memory - Do I need more RAM?

• Graphics and USB devices freezing soon after OS loads

  - by Andrew

  I run Ubuntu/Windows dual boot. Last night I started the upgrade to Ubuntu 12.04, and my computer has not worked since in either Windows or Ubuntu. Here's what I got when I rebooted after the upgrade, and continue to get every time I boot: Gets to GRUB screen OK. Choose Ubuntu - black screen or crazy purple lines. At first I assumed something went wrong with the upgrade (often happens). Choose Windows - works fine, I log in, but soon after that the graphics freeze (sometimes with purple artifacts). The keyboard and mouse (both USB) also lose power at the same instant, and none of the USB ports have power to them. This happens sooner or later every time I boot. Update: the HDD also appears to lose power at the same point. I have tried a live CD, but my computer refuses to boot any CD even after disabling all other boot options in the BIOS. I have disconnected everything except keyboard, mouse, graphics card with one monitor, one RAM sick and HDD; no change. I also took the little battery out to reset CMOS. I am pretty sure no matter how wrong the Ubuntu upgrade went, it wouldn't cause the above symptoms in Windows. So the only explanation I can think of is that a hardware failure occurred at the same time. Some possible causes of this I can think of are: A couple of days before this, I added a third screen (which worked fine). About a week before, my house lost power in a storm (no ill effects over the past few days though). What can I do, other than buy a new motherboard/CPU and hope it works? Unfortunately I don't have another box to swap parts into to test at the moment.

• Locating memory leak in Apache httpd process, PHP/Doctrine-based application

  - by Sam

  I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

• Strange ASP.NET Queue Performance Counters Behavior?

  - by LemurTech

  We have an ASP.NET 2.0 site running in classic mode. I am seeing very strange behavior in the performance counter values. Perhaps these are bugs (I've been all over Google trying to verify this, without much luck), or perhaps it is just my inexperience with monitoring these things. This PerfMon graph (http://imgur.com/Jv5io5J) represents a load test where I add up to 350 virtual users to the site, at a rate of about 1/sec, performing relatively simple page browsing. At the end of the test, I gradually taper off the number of users. This is a 4 CPU server. Machine.config settings for are at the defaults. The solid blue line is ASP.NET Apps v2.x\Requests Executing for the application in question. The profile makes perfect sense, with a quick ramp-up to 32 executing requests (minWorkerThreads x 4CPUs), followed by a slower ramp-up to 48 ((maxWorkerThreads - minWorkerThreads) x 4CPUs). The solid yellow line is ASP.NET v2.x\Requests Queued. Again, this makes sense: after the initial 32 request threads are activated, the queue begins to build as new thread initialization can't keep pace with incoming requests. But as executing requests reaches its highest possible value of 48, the counter for ASP.NET Apps v2.x\Requests Queued (green solid line) suddenly springs to life and maintains step with the yellow counter. As far as I can tell, and with no other apps running on the server, these two counters should have had the same values from the start. One other odd thing: The counter for ASP.NET v2.x\Request Wait Time (dotted yellow line) also does not spring to life until executing requests reaches 48. Shouldn't I be seeing values here from the moment ASP.NET v2.x\Requests Queued begins to build? And likewise, why would ASP.NET Apps v2.x\Request Execution Time (dotted blue) increase significantly only after that peak of 48 is reached? Shouldn't it ramp-up gradually along with queued requests?

• Looking for a short term solution to improve website performance with additional server

  - by Tanim Mirza

  I am working with a small team to run an internal website running with PHP 5.3.9, MySQL 5.0.77. All the files and database are hosted on a dedicated Linux machine with the following configuration: Intel Xeon E5450 8 CPU cores @3.00GHz, 2992.498 MHz, Cache 6148 KB, Cent OS – Red Hat Enterprise Linux Server release 5.4 We started small and then the database got bigger and now the website performance degraded significantly. We often get server space overrun, mysql overloaded with too many calls, etc. We don't have much experience dealing with these issues. We recently got another server that we were thinking to use to improve performance. Since it has better configuration, some of us wanted to completely move everything to the new machine. But I am trying to find out how we can utilize both machine for optimized performance. I found options such as MySQL clustering, Load balancer, etc. I was wondering if I could get any suggestion for this situation "How to utilize two machines in short term for best performance", that would be great. By short term we are looking for something that we can deploy in a month or so. Thanks in advance for your time.
