CPU assignation is very slow and limited

I have the following program:
int main()
    while(true);
    return 0;
}called whileTrue.bin, when I execute it, the output of the line:
while true; do ps -u gimenero -o ruser,pid,ppid,s,pcpu,vsz,osz,comm | grep whileTrue.bin | grep -v grep;sleep 1;done
is the following:

gimenero 14208 29576 O 12.5 27096 3387 ./whileTrue.binIt looks like the CPU assignation occurs very slowly, and it's limited at 12.5%. The other processes are at 1% or less, so almost the whole processor is available for whileTrue.bin.
Is this behavior configurable? It should not behave like this, a while-true loop should jump to the maximum (in this case, near 100%) in like a second or two (when I try this in another plattform, a Tru64 one, it behaves like spected, jumping to 99% in 1 second). This behavior is making everything very slow. Why is this CPU assignation so slow? Why is it limited? Where can I configure this limit and this rate of cpu assignation?

About the 12,5% limit, you're right, we're running on a 8 processor CPU and it considers the whole group to be 100%.

You're also right about the ps average. I tried the following code:
#include <time.h>
#include <stdlib.h>
#include <iostream>
#include <errno.h>
using namespace std;
int main(int argc, char **argv)
    if (argc < 2)
        cout << "Uso: ciclos <tiempo>" << endl;
        return 1;
    errno = 0;
    int lapse = atoi(argv[1]);
    if (errno)
        cerr << strerror(errno) << endl;
        return 1;
    time_t currTime = time(NULL), startTime = currTime;
    time_t lastUp = currTime;
    long i, j;
    int last = 0;
    for (i = 0, j = 0; currTime - startTime < lapse; i++, currTime = time(NULL))
        if (currTime - lastUp > 0)
            cout << "Second " << (j++) << ": Cycles: " << i
                 << " (dif.: " << (int) (i - last) << ")" << endl;
            last = i;
            lastUp = currTime;
            i = 0;
    return 0;
}To measure the amout of cycles/sec at each second, and the results where the following:

  • Firefox very slow and high cpu usage!! (all other browse slow too)

    Sorry, I asked it in 'Newbie Corner' , but still no resolved. so I asked here.
    Hi all,
            when i open a website just as www.sohu.com,   my firefox (3.0.3) hang on, then display the web page very slow , and slow scroll , firefox cpu usage nearly about 100.
            I tried some sloution,like modify /etc/enviroment to set MOD_DISABLE_PANGO=1,
    or disable 'tell me if a web site ...' in firefox security option.
    but still slow.
    some people says it's must because flash or some js.
    but when  i try it in windows or ubuntu, it very fast, not like in archlinux.
    so i think some thing wrong in archlinux.  I need your helps.
    thank you.
    p.s.
    1.  pacman is very fast (the speed of wget about 400k/s)
    2.  gnome web browser like firefox , slow and high cpu.
    3.  the list of output of 'locale'  about 11 lines.
    4.  i have already set host name like wiki says.
    5.   the system is  a new system

  • My MacBook pro is running very slow and unresponsive.

    My MacBook pro is running very slow and unresponsive. I have mid 2010 model running on lion. Past few days it looks very unresponsive. Tried to reinstall lion as clean copy. Still no luck. Any help on this is much appreciated !
    My model has 4 gb ram.

    Things That Can Keep Your Computer From Slowing Down
    If your computer seems to be running slower here are some things you can do:
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • GT70 internet very slow and sluggish when waking from sleep

    My GT70 sometimes is very slow and sluggish to respond when it is awoken from sleep mode. Browsers become unresponsive (hyperlinks don't register as links and require multiple clicks to respond) and internet gets very slow. Speedtest.net reports  .50-3mb/s when it is usually 24mb/s and above.  The hdd also thrashes about and won't calm down for what seems like an eternity.
    This only happens when opening the lid after the machine sits idle for several hours. This is fixed by restarting the machine.
    Does anyone know why this laptop would be behaving like this? it is very frustrating and makes sleep mode pretty much useless.
    cheers,
    -deluxxe

    Quote from: darkhawk on 22-November-13, 13:17:05
    First thing I would do is get CPU-Z and open that after wake-up and seeing if the CPU is running at the speed expected, or if it's stuck at some lower speed.
    thanks for the reply. will try that next time it happens.

  • Premier Elements 4 very slow and frequently crash

    Dear Adobe support staff,
    I've purchased Adobe Premier Elements 4 several yeard ago for an urgnet job I made.
    I didn't use it much because it crashes all the time, and it is very very slow and frustrating. So I've used other software instead.
    Needless to say that I was very dissappointed.
    Now, I want to give it a second chance. but it stiil keep crashing and still very very slow.
    My questions:
    1.  Why does it  crash all the time?  is there is a fix for the problem?
    2.  What kind of  Graphics Card or Video Editing Card do you recommend for my system to work relatively normal ?
    3.  How much will it  cost me to upgrade to version 11 ?
    My system SPEC:
    OS:  Microsoft Windows 7 ultimate  with SP1 (32bit) .
    CPU:  INTEL Core2 QUAD cpu Q9550 , 2.83 GHZ with a 4 GB of RAM.
    Graphics card:  NVIDIA GeForce 9600 GT.
    Motherboard:   MICRO STAR INTERNATIONAL , MODEL MS-7353  3.0,  CHIPSET INTEL X48,
    RAM:  4 GB Dual Channel DDR2, 400 MHZ ,  512 MB memory.
    Please  advice.
    Sincerely yours,
    Shimon Tourgeman.

    For the crashing, this FAQ Entry might be useful. It starts with a general PrE checklist, then goes into computer and OS tuneup, and ends with many links on troubleshooting and finding causes: http://forums.adobe.com/thread/792580?tstart=0
    As for the GPU, any current video card, with at least 1GB of VRAM, will work well. PrE does not place much of a load on the GPU, but it DOES rely very, very heavily on the video driver. Both nVidia and AMD/ATI issue constant driver updates, with nVidia leading the way at this moment.
    Also, while talking about drivers, some users have experienced issues with Win8 drivers. I would wait until SP1 has been released for Win8, before changing to it from Win7. For this reason, I just ordered a new laptop, and specified Win7. As the company, ADK, only builds custom and semi-custom video editing machines, they commented that they will ONLY install Win7 at this time, and have been testing Win8, since the first beta. They do not think that it is yet ready for "prime time."
    Good luck,
    Hunt
    PS - I still use PrE 4.0, but on XP-Pro SP3, and have only crashed it 2-3 times over the years. At least 2 times, it was due to OE on my part. However, my computer is tuned and built for video editing.

  • Very slow and unstable after update...

    After update yesterday, my Arch64 was very slow and unstable... Eclipse IDE crashes, Firefox uses +200mb and Xorg uses +15% of CPU. Xorg lags when I'm going to switch between virtual desktop in KDE... very strange!
    Some confs below:

    I misread that the in kernel driver of v3.12 was working properly. THat way you can figure out what exact change broke performance by testing different development kernels.
    There is an in-kernel driver in staging called rtl8192u. It received a lot of changes in v3.12. Maybe try v3.11 and see if that works?
    it didnt work in kernel 3.12, but with https://aur.archlinux.org/packages/dkms-8192cu/ it worked perfect
    in kernel 3.13 it is horrible both witht he stock driver or with the AUR package.

  • Indesign image display is very slow and jerky

    good morning
    I contacted Adobe Customer Service in Italy because I have big problems with the Creative Suite CS 5.5, in particular with Indesign and in general with the display of images of AI and Acrobat.
    As I work with Indesign image display is very slow and jerky. Even with AI and Acrobat work experience is not good, the images are jerky and there are hesitations in the fluidity of view.
    The software is installed on windows 7 64bit Utlimate, the workstation is very powerful: Supermicro motherboard, dual Xeon E5620 2.4ghz, 16gb ram, SSD OCZ vertex4, PNY Nvidia Quadro 4000.
    The customer service has sent me several tips for email, I have followed all the instructions but I did not get results. In conclusion, when I pointed out that reading on the forums I was not the only one who showed this problem and after discussing about my hardware configuration, they told me that the problem is probably due to the fact that I have two Xeon processors!
    In efects had observed that CS 5.5 on my notebook works better, but I never thought about having problems because the PC is powerful. I checked the CPU and GPU when using Indesign and I could see that uses a single CPU, and most "only 1 core"! But of CPUs in the system there are two for a total of 8 cores. Indesign seems to use only 1/8 of the available computing power ... In addition, practically does not use the GPU (only 10-15%).
    From the customer service was suggested to disable or remove a processor from the system. All this seems to me incredible. I use the workstation for applications that can take advantage of the power of the machine, should I remove the processor whenever I have to use CS 5.5? If things are this way I'm thinking of asking if Adobe buy me a PC with a single processor only for use with CS 5.5 ...
    Thank you.

    Interesting idea, I'll investigate in this direction, I should try to make a mirror of the ssd on a traditional hard drive, exchange them and see if the situation changes. It must, however, be a further factor in the eventual bad combination hardware ... on my laptop I have: windows 7 x64, intel core i7 processor, 16gb of ram, nvidia quadro 3000m, and .... a ssd ocz agility 3, but indesign is more responsive.
    But why indesign should be influenced by the hard-drive? With 16gb of ram and working files on NAS because in design interacts with the hard drive?

  • When starting Thunderbird to retreive my emails it is very slow and eventually no emails show up. Help

    I use Thunderbird to retrieve my emails. When I click on the site at the bottom left hand corner it indicates how many emails are waiting to upload on my page. AVG AntiVirus scans the emails. It starts out very slow and the green bar comes across the bottom right hand corner very slowly. I may get one or two emails but then it just stops and the rest of the emails don't upload on my site. My husband has the same issue as he uses Thunderbird also. Any help will be greatly appreciated. Thank you.

    H Sean,
    Welcome to Apple discussion: )
    What if anything have you tried or have done to trouble shoot the problem.
    Look in your Console, found in the Applications/ Utilities folder for any
    clue, check the console.logs & system.logs, for any clues & paste them in a reply post. Look for items that access the net.
    Do you do any internet clutter cleaning, using a tool, such as OnyX make sure to get the correct version for 10.3.9 if you do download it.
    See Neils User's tip article , on Clearing caches with OnyX
    Do you do any Regular Maintenance/General Troubleshooting ?
    Go to Home~/Library/Caches/Safari cache folder, and Get info on the size of the Safari cache folder, if it is larger then 5 MB's I would trash the entire Safari cache folder.
    ~/Library/Safari folder/Icons folder, what is the size of that folder, if more say 2-3MBS, that could slow things down. These are the icons beside every
    bookmark & URL , when you trash this folder the Icons will all become default
    blue bubbles, the icons will recreate, unless you set the "You -can" Read & Write to Read only, in the "Ownership & Permissions" portion of the "Get info" window. Same is true for the Safari cache folder.
    System Preferences-> Accounts-> Start up items, the more items there the more CPU usage the more spinning you may experience, which items do
    you have there?
    Which version of iTunes are you running, & have you removed the extra files?
    Do you have and problems running Disk permissions repair?
    Please post back.

  • Macbook works very slow and consumes a lot of battery power when closed

    Hi@all
    I hope someone of you can help me. My Mac crashed yesterday. I got a warning saying "there was a problem, your Mac will reboot" (I didn't get the exact words because it vanished quite fast and the MacBook rebooted itself). Since then my Mac is working very slow and freezes every few minutes. I looked at the CPU usage but this is always under 25% so there shouldn't be a programm that causes this problem.
    In addition:
    When I close it, it seems to go to sleep mode normally but is still consuming quite high amounts of battery power and get's warm. When I work with it the temperature stays normal.
    I have a MacBook Pro (mid 2012) with 2.5 GHz Intel Core i5 running with Mavericks.
    It would be great if someone has an idea what could cause this kind of problems.
    Thanks a lot in advance for your suggestions :-)

    sternblume,
    for the high energy consumption in sleep mode, you could try resetting its System Management Controller.
    For the slow working and freezing, you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode.

  • My MacBook (10.5.8) is very slow and has significant problems loading will Snow Leopard (10.6.3) help or make my computer slower?

    My MacBook (10.5.8) is very slow and has significant problems loading will Snow Leopard (10.6.3) help or make my computer slower?
    Also why does my Macbook make so much noise (The noise concerns me because it is so loud it sounds like the laptop will break down or something at any point)?

    It depends on your Macbook model how to open the bottom case.
    Anyway you need to open up the buttom case or keyboard panel to access the CPU fan like following.
    https://www.youtube.com/watch?v=3hHA4DDEvZA
    http://www.ifixit.com/Guide/MacBook+Core+2+Duo+Lower+Case+Replacement/537
    If you think you can't do that by yourself, you'd better bring it to Apple Store Genius Bar or Authorized Servce Shop to tell them about the problem.

  • Netflix /youtube is very slow and jerky

    My macbook pro is a 2.43 GHz intel Core duo with 4GB of memory.  I updated to Maverics and Netfix and youtube became very slow and jerky.
    Even moving the mouse causes probles with playback.
    This does not happen my wifes mac book pro, or my small windows laptop and it did not happen untill I updated to maverics.
    Any suggestions?
    Thanks

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
