  • MySQL PHP | "SELECT FROM table" using "alphanumeric"-UUID. Speed vs. Indexed Integer / Indexed Char

    - by dropson
    At the moment, I select rows from 'table01' using: SELECT * FROM table01 WHERE UUID = 'whatever'; The UUID column is a unique index. I know this isn't the fastest way to select data from the database, but the UUID is the only row-identifier that is available to the front-end. Since I have to select by UUID, and not ID, I need to know what of these two options I should go for, if say the table consists of 100'000 rows. What speed differences would I look at, and would the index for the UUID grow to large, and lag the DB? Get the ID before doing the "big" select 1. $id = "SELECT ID FROM table01 WHERE UUID = '{alphanumeric character}'"; 2. $rows = SELECT * FROM table01 WHERE ID = $id; Or keep it the way it is now, using the UUID. 1. SELECT FROM table01 WHERE UUID '{alphanumeric character}'; Side note: All new rows are created by checking if the system generated uniqueid exists before trying to insert a new row. Keeping the column always unique. The "example" table. CREATE TABLE Table01 ( ID int NOT NULL PRIMARY KEY, UUID char(15), name varchar(100), url varchar(255), `date` datetime ) ENGINE = InnoDB; CREATE UNIQUE INDEX UUID ON Table01 (UUID);

  • How to speed up drawing of scaled image? Audio playback chokes during window resize.

    - by Paperflyer
    I am writing an audio player for OSX. One view is a custom view that displays a waveform. The waveform is stored as a instance variable of type NSImage with an NSBitmapImageRep. The view also displays a progress indicator (a thick red line). Therefore, it is updated/redrawn every 30 milliseconds. Since it takes a rather long time to recalculate the image, I do that in a background thread after every window resize and update the displayed image once the new image is ready. In the meantime, the original image is scaled to fit the view like this: // The drawing rectangle is slightly smaller than the view, defined by // the two margins. NSRect drawingRect; drawingRect.origin = NSMakePoint(sideEdgeMarginWidth, topEdgeMarginHeight); drawingRect.size = NSMakeSize([self bounds].size.width-2*sideEdgeMarginWidth, [self bounds].size.height-2*topEdgeMarginHeight); [waveform drawInRect:drawingRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1]; The view makes up the biggest part of the window. During live resize, audio starts choking. Selecting the "big" graphic card on my Macbook Pro makes it less bad, but not by much. CPU utilization is somewhere around 20-40% during live resizes. Instruments suggests that rescaling/redrawing of the image is the problem. Once I stop resizing the window, CPU utilization goes down and audio stops glitching. I already tried to disable image interpolation to speed up the drawing like this: [[NSGraphicsContext currentContext] setImageInterpolation:NSImageInterpolationNone]; That helps, but audio still chokes during live resizes. Do you have an idea how to improve this? The main thing is to prevent the audio from choking.

  • Python2.7: How can I speed up this bit of code (loop/lists/tuple optimization)?

    - by user89
    I repeat the following idiom again and again. I read from a large file (sometimes, up to 1.2 million records!) and store the output into an SQLite databse. Putting stuff into the SQLite DB seems to be fairly fast. def readerFunction(recordSize, recordFormat, connection, outputDirectory, outputFile, numObjects): insertString = "insert into NODE_DISP_INFO(node, analysis, timeStep, H1_translation, H2_translation, V_translation, H1_rotation, H2_rotation, V_rotation) values (?, ?, ?, ?, ?, ?, ?, ?, ?)" analysisNumber = int(outputPath[-3:]) outputFileObject = open(os.path.join(outputDirectory, outputFile), "rb") outputFileObject, numberOfRecordsInFileObject = determineNumberOfRecordsInFileObjectGivenRecordSize(recordSize, outputFileObject) numberOfRecordsPerObject = (numberOfRecordsInFileObject//numberOfObjects) loop1StartTime = time.time() for i in range(numberOfRecordsPerObject ): processedRecords = [] loop2StartTime = time.time() for j in range(numberOfObjects): fout = outputFileObject .read(recordSize) processedRecords.append(tuple([j+1, analysisNumber, i] + [x for x in list(struct.unpack(recordFormat, fout))])) loop2EndTime = time.time() print "Time taken to finish loop2: {}".format(loop2EndTime-loop2StartTime) dbInsertStartTime = time.time() connection.executemany(insertString, processedRecords) dbInsertEndTime = time.time() loop1EndTime = time.time() print "Time taken to finish loop1: {}".format(loop1EndTime-loop1StartTime) outputFileObject.close() print "Finished reading output file for analysis {}...".format(analysisNumber) When I run the code, it seems that "loop 2" and "inserting into the database" is where most execution time is spent. Average "loop 2" time is 0.003s, but it is run up to 50,000 times, in some analyses. The time spent putting stuff into the database is about the same: 0.004s. Currently, I am inserting into the database every time after loop2 finishes so that I don't have to deal with running out RAM. What could I do to speed up "loop 2"?

  • How to know if your computer is hit by a dnschanger virus?

    - by kira
    The Federal Bureau of Investigation (FBI) is on the final stage of its Operation Ghost Click, which strikes against the menace of the DNSChanger virus and trojan. Infected PCs running the DNSChanger malware at unawares are in the danger of going offline on this coming Monday (July 9) when the FBI plans to pull down the online servers that communicate with the virus on host computers. After gaining access to a host PC, the DNSChanger virus tries to modify the DNS (Domain Name Server) settings, which are essential for Internet access, to send traffic to malicious servers. These poisoned web addresses in turn point traffic generated through infected PCs to fake or unsafe websites, most of them running online scams. There are also reports that the DNSChanger virus also acts as a trojan, allowing perpetrators of the hack attack to gain access to infected PCs. Google issued a general advisory for netizens in May earlier this year to detect and remove DNSChanger from infected PCs. According to our report, some 5 lakh PCs were still infected by the DNSChanger virus in May 2012. The first report of the DNSChanger virus and its affiliation with an international group of hackers first came to light towards the end of last year, and the FBI has been chasing them down ever since. The group behind the DNSChanger virus is estimated to have infected close to 4 million PCs around the world in 2011, until the FBI shut them down in November. In the last stage of Operation Ghost Click, the FBI plans to pull the plug and bring down the temporary rogue DNS servers on Monday, July 9, according to an official announcement. As a result, PCs still infected by the DNSChanger virus will be unable to access the Internet. How do you know if your PC has the DNSChanger virus? Don’t worry. Google has explained the hack attack and tools to remove the malware on its official blog. Trend Micro also has extensive step-by-step instructions to check if your Windows PC or Mac is infected by the virus. The article is found at http://www.thinkdigit.com/Internet/Google-warns-users-about-DNSChanger-malware_9665.html How to check if my computer is one of those affected?

  • Why would the 'show processlist' command speed up normally slow requests to my remote DB? (connected via VPN)

    - by Hakan B.
    I am running a local Django development server that connects to a remote MySQL server via a VPN (IPSec). Request times are awfully slow and I consistently see timeouts. Attempting to diagnose the problem, I logged in to the remote database and ran: show full processlist Immediately, the local server went from idle to working. The page had not yet completely loaded, but progress had been made (debug logs confirm this). When I ran 'show full processlist' several times more in succession, the request completed quickly. I can currently reproduce this - unless I run 'show full processlist' over and over on the remote server, my local request usually times out. Does anyone have any idea why this would happen? I'm running Django 1.3 and OS X 10.7. Note: I realize this may be entirely not be a question with a clear-cut answer and is probably my fault, but it is odd and reproducable, so I hope someone can at least point me the right direction. Thanks 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!

  • NIC Bonding/balance-rr with Dell PowerConnect 5324

    - by Branden Martin
    I'm trying to get NIC bonding to work with balance-rr so that three NIC ports are combined, so that instead of getting 1 Gbps we get 3 Gbps. We are doing this on two servers connected to the same switch. However, we're only getting the speed of one physical link.

  • USB transfer speed "logarithmically" decreases. Why and can it be improved?

    - by starship
    I have an external hard drive. Just today I tried to copy a bigger file (it was film of ~230 MB) and at first it rushed up until ~70%. There is started decreasing. At first it started at around 56 MB/s Then it rapidly dropped to 23 MB/s (File transfer was 70% complete) Then it slowly started decreasing until it was around 2 MB/s (File was ~90% complete) When it finished the transfer it was slightly above 1.5 MB/s. To describe it graphically: If you drew a curve of the decrease it would probably resemble the graph of a logarithm function So, what I'm really asking is: "Why does this happen?" and "Is there a way around it?" Thank you!

  • How can I speed up my Windows Server 2008 VPN Connection?

    - by Pure.Krome
    So I've installed VPN service that comes with Windows Server 2008. Works perfectly, etc. When a client remote desktops to one of the private servers at the office, via VPN .. it's pretty slow. Now - how long is a piece of string? So before I get all the obligatory checks, I'll list the things from Mr. Obvious: Our modem/router (fritz!box) has a data/graph that shows incoming and outbound bandwidth. Both directions are barely getting used when a client has RDP'd via VPN. Our office internet connection is running at 21,9 Mbit/s download 1,3 Mbit/s upload. I feel like it's maxing at .. modem speeds ?? Is there any tricks I can do to confirm this and possibly even fix this?

  • What can I do to speed up my HTC Hero?

    - by Nick Bolton
    When I first got my HTC Hero phone it was very fast. But after a couple of weeks it's become slow. Typically (on any device), I've noticed that this is caused by having too much running at once... Is there a way I can limit the number of applications that are open? I think there's a task manager application in the market, so I'll try this. Does anyone have any further suggestions?

  • Eclipse: would more CPU cores with HyperThreading help increase speed?

    - by Dylan
    I'm programming a very large project in Eclipse. Right now I use a dual core machine with 2GB RAM, but Eclipse is sometimes busy for minutes (refreshing/indexing/building), so I'm upgrading to a new machine (with 16GB RAM and an SSD). Now I must choose between an Intel 2500K or an Intel 2600K that has HyperThreading. The price difference is about $100. Would that be worth it, for Eclipse, or is more memory/faster drive much more important for Eclipse ? Can Eclipse make use of the HyperThreading at all?

  • Is there any program (or code, any language) that will mute all of the microphones on my computer?

    - by Sean
    Is there any program (or code, any language) that will mute all of the microphones on my computer? If it is code, please make it as simple as possible, the only language I know is C# and I am still VERY new to it. I just want to setup some way to mute my microphones from a hotkey/shortcut, and if I can just find a program that can do, I will be set. As I said, I can also do a little bit if it is in C#, but the only code I have seen before for this, was miles long (atleast to me). My goal, is I just want a program that opens up, and toggles the mute on the microhpones (all of the system audio input) then closes. That is it, very simple. Thank you to anyone who trys to helps me! EDIT: Yes, I am using Windows. I am using Windows 7 32-bit. I already know that I can go into the volume mixer and do it that way, but I need to do this while running a full screen application, and it is a hassle to have to exit fullscreen, open the volume mixer, the click the mute icon, then go back into full screen and the the whole thing over again to unmute it. And I will be toggling back and forth quite often, so it just takes alot to do that so much.

  • Why is a SUBST'd drive inaccessible via shortcut or Run menu, but works fine from My Computer?

    - by Kev
    I have shortcuts to C:, D:, and E: in my quick launch bar. C and E work fine when I click on them, but D does nothing (that I can see) when I click on it. D and E are both SUBST'd drives pointing to folders that happen to be network shares. (I do this rather than mapping them so it doesn't have to go through the network layer--that way it works faster and I still get recycle bin functionality, etc.) If I go Start-Run and type D: or D:\, I get an error box saying This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel. If I go to My Computer and double-click the D drive, it comes up fine. Also, if I type \\servername\sharename pointing to the same place, it comes up fine. This just started happening this morning, out of the blue. It has been working fine ever since I set it up. Why might this be?

  • BizTalk/MQ - DCOM was unable to communicate with the computer xxx using any of the configured protocols

    - by NealWalters
    I've read the other questions on this same error, but don't see a close match to this scenario. We got 18 of these last night between 12:17:13 and 12:39:37 on Win 2008/R2. It caused us to lose connectivity between BizTalk 2010 and WebSphere MQ machine. All our BizTalk machines (Prod, QA, Train, etc...) got the messages at the roughly same time and in the same quantity (about 18 of them). Computer xxx is the WebSphere MQ machine. What could cause this in the middle of the night? The servers are configured and running in Prod for a couple of years. There is no Win Firewall running, and servers are practically on the same rack. Could a run-away or 100% utilized CPU on the WebSphere MQ cause this issue? What else could cause it? BizTalk did NOT auto-recover from this situation. The above was followed by thousands of this message in the BizTalk event logs: The adapter "MQSeries" raised an error message. Details "Error encountered on Queue.Get Queue name = MyQManager/MyQueueName Reason code = 2354.". We restated BizTalk host instances, and it did not come back right away. It seemed we had to stop host instances for about two minutes, then start them.

  • Does Antivirus2009 or Antivirus360 automatically install on your computer and if so how?

    - by sergey
    I run Firefox on Vista, and unfortunately I got tricked (through a deceptive google result) into going to a page containing one of those fake "Your Computer Has all of this Spyware on it!" pages. I tried manually closing the tab, but it had a "Are you sure you want to navigate away" JavaScript alerts (HATE THOSE). So I clicked "OK," and the tab closed. Then I closed firefox altogether and rebooted. Now, before I could close the tab, it did prompt me to download a file, but of course I choose not to, and checking my downloads folder, nothing new is there. Also, even if I ?did? download it, ?I? would still have to choose to run it by double clicking on it for it to install itself, right? Also, I ran Malware Bites and Windows Defender and both said everything was fine. From this I would normally believe I am safe, but I have read everywhere that this thing "automatically installs" itself and that it is a bitch to get rid of. Is it really possible for this thing to dig in if you are running firefox and didn't choose to download it or run it after downloading?

  • Copy past speed very slow for a large number of tiny files on Windows but not on linux

    - by Arno2501
    I've got this folder which contains 15'000 of tiny images (around 400 bytes each). If I copy past this folder on my laptop (Windows 7, i7 latest gen, superfast ssd) it takes about 30 seconds (yes for 7 megs !!!) the average transfer rate is 400 KBytes / second which is so slow. I mean my usual transfer rate is more like hundreds of MBytes per second !!! I get the same problem on my servers (Windows 2003, 2008 /r2) and on every Windows box that I could get my hands on. On the other hand if I do the same on a linux box (debian base, Ext3 FS) (which runs on the same SAN than all the windows servers I've tested) It's nearly instantaneous !!! I'm pretty sure the size / number of the files may stress such filesystem more than another but such differences !? Why is that ? Why is it so slow on the windows boxes (more that 30 sec for 7 MB) and so fast on the linux ones (one sec or so) (I mean this was not a hardlink that I've created it was a true copy). Is it a normal behaviour or something unusual ?

  • Important hardware components to avoid bottlenecks/improve speed on a laptop?

    - by joelhaus
    Looking for a powerful general use (including web development) laptop running Windows. Price points seem to be all over the place. Many less powerful machines are priced much higher than machines with better specs. How does one navigate this market? Are there any unpublished/under-publicized specs/bottlenecks you look for? Understanding that hardware improves over time, is there an efficient ratio that can be used (or something similar, like Windows Experience Index?) which will indicate how powerful a system is? Thanks in advance! P.S. Here is an example from a laptop released on September 17, 2010. Can anyone pick apart these specs? Is there missing information you would be looking for? OS: Win 7 Display: 16.4" LED backlit Processor: Intel Core i7-740QM, 6MB L3 Cache RAM: 6GB DDR3 1333MHz (8GB max.) Graphics: NVIDIA GeForce GT 425M (1 GB of dedicated DDR3) HDD: 500GB 7200RPM SATA Hard Drive Removable Disc: Blue-ray with DVD±R/RW Misc: webcam/mic/speakers/bluetooth (via Sony Vaio VPC-F137FX/B)

  • Why can't gif images copy at a reasonable speed on this dell laptop with XP?

    - by alt234
    I've got this somewhat old Dell Latitude D810. Strangest thing... If I try to copy anything that has gif files in it the gif files take forever. Like a few minutes per gif regardless of size. Everything else copies fine. I notice this when copying files off our network, copying off multiple external drives, and even when files are copying during an installation process. I'm on Windows XP Pro service pack 3. I've never seen anything like this before. Anyone else?

  • Is there any way to distribute x264 encoding jobs across multiple computers (to increase the encoding speed)?

    - by Breakthrough
    Does anyone know of a current, active solution to encoding x264 videos across many computers (via the network) to increase encoding FPS? Brownie points for cross-platform and open source, but just so you all know, I usually use Windows. Programs that I have heard of, and why I do not believe they are suitable: x264farm: Not actively developed. Good interface, but does not support two-pass encoding, and fails with newer x264 builds. ELDER: Again, not actively developed, but my issue was that it didn't work with new x264 builds, and it was very difficult to configure (read: randomly stopped working). While I don't absolutely need a program which is being actively developed, I would like one that supports two-pass encoding, and works with new(er) x264 builds. Additional information: So far, I've offered (and awarded!) two separate bounties on this question since I first posted it over two years ago, and I still haven't found a solution to this problem. What I'm looking for basically is a simple program to allow me to encode x264 videos using the processing power of multiple computers connected over a LAN. Furthermore, it would be nice if it worked with new(er) x264 builds, and supported two-pass encoding. If at any time someone has an updated answer, or a new solution to this problem, please post it and it will be given some consideration.
