IE Intense CPU usage

Hey all,
Still new to the Spry framework and loving it, but I've seen
to hit a slight bump.
Basically I have a page that loads the XML data from a
servlet, and the data is constantly reloaded every 5 seconds.
Here is the code i've opted for to perform the update:
var data = new Spry.Data.XMLDataSet("data?show=1",
"data/row");
function getData() {
data.setURL('data?show=1'); data.loadData();
window.setInterval("getData()", 5000);
*Also disabled caching in SpryData.js
Problem is, just after a bit, IE runs sluggishly and
TaskManager has the CPU usage from 22%-99%.
On the other hand, it runs perfectly on FireFox. I was
wondering if there would be a better alternative to perform the
update or a fix?

Hey Xephyr,
Try:
new Spry.Data.XMLDataSet("data?show=1", "data/row", {
useCache: false, loadInterval: 5000 });
And see if that works better.
Thanks,
Don

  • [Debugging] - how to avoi intensive CPU usage with debug command

    Hi all !
    I hope you're well !
    I'm just wondering if there is a mean to avoid the increase of CPU usage when using the debug command. More precisely I would like to know if it exists something to avoid the CPU to saturate and to allow vital process to be prioritary for using the CPU, just like a QoS mecanism but to classify the process in order of importance.
    Thanks a lot in advance !

    some time ago this document was posted on CSC which give an excellent overview on how to savely enable debug commands:

  • High CPU usage with Coherence 3.5.0 cluster node

    We're noticing sustained high CPU usage on one of our Coherence nodes - this happens after running a job that pretty intensively interacts with the cache. The jobs complete, however we still see the Coherence process using approximately the equivalent of one core's worth of CPU. I took a couple of thread dumps about fifteen minutes apart, and the only noticeable differences are within the PacketListener1 and PacketListenerN threads - they're holding locks on different DatagramPacket instances, which suggests to be that this may be the piece of code that is looping.
    There are two other cache nodes in this particular cluster - both of them on a different machine - and neither of them are exhibiting the same CPU utilization.
    Environment:
    Coherence 3.5.0

    Has anyone encountered this scenario before?
    Here's a copy of the two thread dumps:

  • High CPU usage

    I'm using Vibe Desktop Version 1.0.1 (17445) on Mac OSX 10.8. During file syncronization there is a realy high CPU load:
    Does anybody else see high CPU usage while using Vibe Desktop?

    I'm the Novell developer responsible for Vibe Desktop and I'm sorry for the delayed response...I've been out of the office. Can you give me a little more information? I want to get a better feel for when the high CPU usage occurs.
    Approximately how many files are synced to your Desktop?
    When you click on the icon in the menu bar and select "Synchronize Now", how long does it take and how is the CPU usage? The first time you sync all the files down to your desktop can take some time, but once everything is in sync, forcing it to synchronize should not be very resource intensive. Is the high CPU utilization only when it is has files to download, or is it also high when there is nothing to download?
    When Vibe Desktop is not syncing, it's still watching the file system for changes you make to the local copies of the files. Do you see noticeable CPU utilization when Vibe Desktop is not syncing?

  • High CPU usage (more than 100%) while running video applications

    Hello everyone,
    I desperately need help with this.
    I have a late 2007 White Macbook running Mac OS X 10.6.8 :
    Model Name:          MacBook
      Model Identifier:          MacBook2,1
      Processor Name:          Intel Core 2 Duo
      Processor Speed:          2 GHz
      Number Of Processors:          1
      Total Number Of Cores:          2
      L2 Cache:          4 MB
      Memory:          3 GB
      Bus Speed:          667 MHz
    The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU  usage thing started (according to my knowledge)
    I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.

    I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
    Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
    From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
    I love my Macbook... don't want to part with it.

  • MacBook Air 11" Mid 2011 (Fan & CPU Usage & Kernel_task)

    Hello everyone.
    I have a small problem with my Mac which is about its fan noise and CPU usage.
    It was running FLAWLESSLY until like last couple of days after OS update where I started to notice really high CPU and Fan usage.
    But first, system specification:
    1.6 Ghz Intel Core i5 Processor
    4GB 1333 MHz DDR3 Memory
    Intel HD Graphics 3000 384 MB Graphics Card
    Mac OS X Lion 10.7.5
    128GB SSD Storage
    For some reason my MacBook Air started to have these "high intensity work" moments when a process called "Kernel_task" started to eat up to 600% of the CPU !
    Now I can imagine it's just a software issue since it started to occur after I updated my OS via Software Application and my Flash Player and the rest of my software is up-to-date too but has any of you had this problem before ?
    I do not play on my MacBook Air, there are only two things I do - I use Safari and some Adobe software (Photoshop/Flash/Dreamweaver/Illustrator/InDesign/Fireworks) and that's all.

    The kernel is using excessive processor cycles. Below is a partial list of causes for this condition.
    Throttling
    When it gets high temperature readings from the hardware, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce heat dissipation. This condition can be due to an accumulation of dust, to high ambient temperature, or to the malfunction of a cooling fan or temperature sensor. Note that if the problem is caused by a faulty sensor that reads too high, there may be no actual overheating.
    The Apple Hardware Test, though not very reliable, is sometimes able to detect a bad fan or temperature sensor.
    Using Apple Hardware Test
    Encryption
    Transferring large amounts of data to or from an encrypted disk image or FileVault volume may put an extra load on the kernel. If both the source and the destination are encrypted, the load may be doubled. If you transfer data from an encrypted disk image on an encrypted partition to another such image on another encrypted partition, the load may be quadrupled.
    This issue probably doesn't affect late-model Macs with an Intel i-series, recent Xeon, or later processor. Those processors support hardware-accelerated encryption. You can determine what kind of processor you have by selecting About This Mac from the Apple menu in the menu bar.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or booting in safe mode (with the shift key held down at the startup chime.) Note, however, that disabling a system modification without removing it or booting in safe mode may not be as easy as you think it is.
    Corrupt NVRAM or SMC data
    In some cases the condition has reportedly been cleared up by resetting the NVRAM or the SMC. I can't confirm.

  • Lightroom Mobile Sync - Extremely High CPU Usage/Sync Process Causes LR To Lag

    Since my other thread doesn't seem to be getting any responses, I'm pasting what I've found here. Please keep in mind I am not a beginner with Lightroom and consider myself very familiar with Lightroom's features excluding the new mobile sync.
    1st message:
    I'm on Lr 5.5 and using the 30 day trial of Adobe CC to try syncing one collection of slight more than 1000 images. Despite already having generated the Smart Previews, I can see my CPU crunching through image after image (the rolling hills pattern in the task manager) while doing the sync. I was assuming, since I already created the Smart Previews, that the sync of this collection would begin immediately and be done by simply uploading all of the existing Smart Previews. The Smart Previews folder of the catalog is 871MB and has stayed the same despite the CPU obviously doing *something*. As it is now, the sync progress is incredibly slow, almost at a pace like it's actually exporting full-res JPGs from the RAW images (as a comparison only, I know this should not be what it's actually doing).
    Another side effect of this is that I'm basically unable to use my computer for other tasks due to the high CPU utilization.
    Win 7 x64 / Lightroom 5.5
    Intel i5 2500k OC'd 4.5GHz
    16GB RAM
    SSD for OS, separate SSD for working catalog and files
    2nd message:
    As a follow up, now Lightroom thinks all 1026 photos are synced (as shown in "All Sync Photographs" portion of the Catalog though all images after the 832nd image show the sync icon per image stuck at "Building Previews for Lightroom Mobile" and the status at the top left corner has been stuck at "Syncing 194 photos" for over 12 hours. Is there no option to force another sync via Lightroom Desktop and also force the iOS app to manually refresh (perhaps by pulling down on the collections view, like refreshing via the Mail app)?
    3rd message:
    One more update, I went into Preferences and deleted all mobile data, which automatically signed me out of Adobe CC and then I signed back in. Please keep in mind the Smart Previews were long generated before even starting the trial, and I also manually generated them again (it ran through quickly since it found they were already generated) many times. Now that I'm re-syncing my collection of 1026 images, I can clearly see Lightroom using the CPU to regenerate the Smart Previews which already exist. I have no idea why it's doing this except that it's making the process of uploading the Smart Previews extremely slow. I hope this time around it will at least sync all 1026 images to the cloud.
    4th message:
    All 1026 images synced just fine and I could run through my culling workflow on the iPad/iPhone perfectly. Now I'm on a new catalog (my current workflow unfortunately uses one catalog per event) and I see the same problem: Smart Previews already generated but when syncing, Lightroom seems to re-generate them again anyway (or take up a lot of CPU simply to upload the existing Smart Previews). Can anyone else chime in on what their CPU utilization is like during the sync process when Smart Previews are already created?
    New information:
    Now I'm editing a catalog of images that is synced to Lightroom Mobile and notice that my workflow has gotten even slower between photos (relative to what it was before, this is not a discussion about how fast/slow LR should perform). Obviously Lightroom is syncing the edited settings to the cloud, but I can see my CPU running intensively (all 4 cores) on every image I edit and the CPU utilization graph looks different than before I started using LR mobile sync. It still feels like every change isn't simply syncing an SQLite database change but re-generating a Smart Preview to go with it (I'm not saying this is definitely what's happening, but something is intensively using the CPU that wasn't prior to using LR Mobile).
    For example: I only update the tint +5 on an image. I see the CPU spike up to around 30-40%, then falls back down, then back up to 100%, then back down to another smaller spike while Lightroom says "Syncing 1 photo".  I've attached a screenshot of my CPU graph when doing this edit on just one image. During this entire time, if I try to move onto edit another image, the program is noticeably slower to respond than it was prior to using LR mobile, due to the fact that there appear to be much more CPU intensive tasks running to sync the previous edit. This is proven by un-syncing the collection and immediately the lag goes away.
    I'd be happy to test/try anything you have in mind, because it's my understanding that re-syncing photos that are edited that are already in the cloud should be simply updating the database file rather than require regenerating any Smart Previews or other image data. If indeed that's what it should be doing, then some other portion of LR is causing massive CPU usage. If this continues, I will probably not choose to proceed with a subscription despite the fact that i think LR mobile adds a lot of value and boosts my workflow significantly if it wasn't causing the program to lag so badly in the process.
    I know this message was incredibly long and probably tedious to read through so thanks in advance to anyone who gets through it

    Thanks for reporting. Just passed  along your info to some of our devs. One of the things that needs to be created (beside smart previews) during an initial sync are thumbnails + previews for the LrM app - Guido
    Hi Guido,
    Thanks for pointing this out. I realized the same thing when I tried syncing a collection for offline mode and found out the required space sounded more like Previews + Smart Previews rather than just the Smart Previews.

    Hi Jeff, are your images particularly large or do you make a lot of changes which you save to the original file as part of your workflow?
    The CPU usage is almost certainly from us uploading JPEG previews not the Smart Previews - particularly during develop edits as these force new JPEG previews to be sent from Lightroom desktop, but would not force new Smart Previews (unless the develop edits are modifying the original file making us think the Smart Preview is out of date) to be sent.
    Guido
    My images are full-resolution ~22mp Canon 5D Mark III RAW files so they're fairly large. Even if I only make one basic change such as exposure changes, I saw the issue. By "save to the original file" I'm assuming metadata changes such as timestamps, otherwise edits to the images aren't actually written to the original file. I'm only doing develop module edits so I shouldn't be touching the original file at all at this point in my workflow.
    I think it makes sense now that you mention that new JPEG previews need to be generated and sent to the cloud due to updated develop edits. My concern is that this seems to be done in real-time as opposed to how Lightroom Desktop works (which is to render a new Standard Preview or 1:1 Preview on demand, which means only one is being rendered at any given time while viewing it in Loupe View or possibly 2 in Compare View). If I edit, for example, 10 images quickly in a row, once the sync kicks in a few seconds later, editing the 11th image is severely hindered due to the previous 10 images' JPEG previews being rendered and sync'd to the cloud (I'm assuming the upload portion doesn't take much CPU, but the JPEG render will utilize CPU resources to the fullest if it can). Rendering Standard/1:1 Previews locally and being able to walk away while the process finishes works because it is at the start of my workflow, but having to deal with on-the-fly preview rendering while I'm editing greatly impacts my ability to edit. Perhaps there can be a way to limit max CPU utilization for background sync tasks?
    It may help to know that I'm running a dual-monitor setup, with Lightroom on a 27" 2560x1440 display maximized to fit the display (2nd display not running LR's 2nd monitor). Since I'm using a retina iPad, the optimal Standard Previews resolution should be the same at 2880 pixels.
    Thanks again for the help!

  • Hi CPU usage in ABAP coding

    Hello,
    I have a custom program (programmed by somebody else) which is churning away all day long and consuming between 50% and 70% CPU as seen in the 'top' command. I'm on HP-UX with 8 CPUs installed. The CPU usage is consistently at this level. (I matched the PID from SM50 with the PID in 'top')
    I ran abap traces in ST12 which found that between 60% and 70% of the time was spent in the following coding:
    773       IF SY-SUBRC <> 0.
    774         LOOP AT GIT_ZTABLEA TRANSPORTING NO FIELDS
    775           WHERE KUNNR      =  PC_KUNNR     "CUSTOMER CODE゙
    776             AND ZZVCGRTNFG IN P_DRTNFG     "FLAG゙(SELECTION CRITEREA)
    777             AND ZZVCGSTPFG IN P_DSPDFG .   "QUIT FLAG゙(SELECTION CRITEREA)
    778           EXIT.
    779         ENDLOOP .
    780                                                                               
    781     *  
    782         PI_SUBRC = SY-SUBRC .
    783         RETURN .
    784                                                                               
    785     *
    786       ELSE.
    787         LOOP AT GIT_ZTABLEA TRANSPORTING NO FIELDS
    788           WHERE ZZVCGGRPID =  GFC_TABLEB-ZZVCGGRPID "GROUP ID
    789             AND ZZVCGRTNFG IN P_DRTNFG               "FLAG゙(SELECTION CRITEREA)
    790             AND ZZVCGSTPFG IN P_DSPDFG.              "STOP FLAG゙(SELECTION CRITEREA)
    791           EXIT.
    792         ENDLOOP .
    I guess the idea here is to just find the number of rows in GIT_ZTABLEA for certain conditions.
    Is there a simple and less intensive way of achieving this?
    (apologies in advance for foreseen dumb questions. I'm very new to coding).
    Peter

    > LOOP AT GIT_ZTABLEA TRANSPORTING NO FIELDS
    > 775 WHERE KUNNR = PC_KUNNR "CUSTOMER CODE゙
    > 776 AND ZZVCGRTNFG IN P_DRTNFG "FLAG゙(SELECTION CRITEREA)
    > 777 AND ZZVCGSTPFG IN P_DSPDFG . "QUIT FLAG゙(SELECTION CRITEREA)
    sorted table ... is the usual answer but not in this case.
    You should check the IN P_DRTNFG "FLAG゙(SELECTION CRITEREA) ?
    What does it mean? I don`t undterstand the flag.
    With the IN conditions I doubt that there is any optimziation possible, it will always scan.
    If the two IN-flag are really flags then it should be possible to write equal condition
    and get something
      WHERE k = a AND z1 = b AND z2 = c.
    The can be solved with sorted tables.
    And from the coding you show with will exit after the first solution, so a READ would then also
    be enough. The LOOP is only used because the WHERE is only possible with the LOOP.
    but a LOOP is not really necessary because it check only the first solution.
    So please revise the logic.
    Then it will become really fast.

  • Only max 30% cpu usage when rendering

    I making an animation that I have done in 3dsMax and save it as a .png sequence. Have done the editing in Premiere cs3, but when I export it with Adobe media encoder as .wmv, it only uses max 30% of the CPU, I have a quadcore 9550, and Vista buisniess64 with 8GB ram.
    I have tried to de-select de-interlace option in the output tab as suggested from other forums.
    But the strange is when I export from the same timeline and have a clip from the HDV camera the CPU goes up to 100%. Why does not premiere uses 100% the whole time?

    Maybe the extra CPU usage is related to the HDV decoding process, which is probably more intensive than PNG decoding... Or, the PNG reader is not multi-threaded at all and this "bottleneck" is slowing down the entire process. ???
    Also: Do not check the "deinterlace" box unless you want to deinterlace and even then you should perhaps look for other options. Premiere's deinterlacer is utter garbage.

  • Satellite A45 - CPU usage is high and applications slow

    Hi all,
    I'm trying to debug a hardware problem on my Toshiba Satellite A45. I'm running Ubuntu 10.04, but I don't believe this is OS or software related.
    THE PROBLEM: CPU usage is high and applications slow to a crawl after using a memory intensive application for a few minutes, i.e. viewing a video or playing a game. Basically, anything that might use the screen a lot. If instead I work only from a command prompt, even when the application might be doing a lot of work, I don't encounter this problem. After shutting down all application, CPU usage is still higher than normal (90% idle, should normally be about 99% idle).
    Xorg typically now showing about 6% usage (normally < 2%). If I at any time after this try to work in any application, usage is still bogged down. Only a reset gets me back to normal.
    Note: My system had always worked fine, and I had not done any software installation or changes when this started happening.
    However, the laptop did go through an 800 mile round trip in the back of the car in a padded laptop bag.
    DEBUG: This doesn't seem to be RAM as I have replaced RAM and reseated the RAM, and the problem still occurs. This doesn't seem to be the Hard Drive as I can try to run from a Live CD (no HDD usage) and everything still slows to a crawl.
    HELP: I'm not sure how to debug from here.
    I don't have extra bits of hardware to do swaps.
    Any ideas how to further debug this?
    Thanks,
    Grommit

    Hi grommit
    What do You think about the possibility that your PC is becoming overheated?
    To me this sounds like such a scenario.
    Your using an application which is intensive - which makes the unit warm up a lot probably.
    After that everything is sluggish. This is what may happen when cooling is not sufficient - the CPU is throttled to reduce heat generation. And the effect is that the unit works pretty slow.
    May I suggest that You try to let the unit be off for some time before trying it again - I don't know your possibilities, but I would put it on the balcony or on the floor below an open window too cool it really much.
    Then try again from whatever media you like.
    The result? Good performance for a while again? Then either clean the cooling module yourself or have a repair workshop do this for You.
    Good luck and stay with Linux! :)

  • Drop in CPU Usage

    Hello Apple family,
    I'm having an issue with my Macbook that is rather surprising. Couple days ago I formatted it since it was almost 3 years since the last one and it was running a Lion install on top of a Snow Leopard install and it was in need of a good summer cleaning. I also had noticed that some of the more heavy tasks I was probably making on it were a bit slow, as in casual gaming and watching videos. So I started a fresh install, here is basically everything I installed:
    I also installed via Homebrew: git and postgresql (and their dependecies).
    Other little things I've installed or changes I've made:
    Installed OSX FUSE
    Installed Apple Command Line Tools
    Installed Zend Framework
    Disabled Dashboard
    When I finally reached running a game, I got the exact same issue I was having before the format, and let me describe that. At first I start running the task and it behaves very well, all computer is fluid no matter what.
    The problem occurs after a more or less 30 seconds: the cpu usage drops. I don't see any other process taking its place or fighting for the same resources, the only process noticed that rises a bit more is kernel_task (it jumps from 5-6% to 10-12%), but I guess its normal since we are talking about more intensive tasks for the kernel. Here is a some screenshots of the problem playing Heroes of Newerth (I'm using atMonitor and the Apple Activity Monitor).
    Normal behavior, high CPU usage
    CPU usage drops
    CPU usage comes back to normal
    I also had this same problem in other games (Swords and Soldiers e.g.) and also watching flash videos (ESPN.com).
    Lets focus on this screenshot in particular. At the moment of the screen shot you can see the process is behaving normally: processor is at 77%, GPU is at 46% and FPS are at 27. But if you take a look at the panel on the right side, you can see the history before that:
    CPU dropped to 10-15% and before that was on the values that were expected.
    Same thing for GPU: at the moment is at 46%, but before that was at 5% and at the start was at 46% as expected.
    FPS also oscillate from 27FPS when the system is running good, to 5FPS when the system is running "low". I guess its a consequence of the other 2 behaving abnormally.
    Also worth notice, the RAM is never near full (as you can see from the screenshot above it stays around 50%); and the log (any of them) are not displaying any message when the system "drops".
    Some procedures I already took:
    Reset PRAM, SMC
    Apple Hardware Test: It hang up 2 times, both at the same spot: logic board
    Repaired disk and disk permissions (from the boot DVD)
    Reseted Spotlight index (it was my first suspicion that was wrong after all)
    I'm really hopeless here. I've googled thousands of stuff, but they are all the opposite of my issue - usually complaining about high CPU usage. Hope someone can point me into some direction. I hope the post has all the information needed, if you need anything else just ask.
    Thank you all.
    PS: Sorry about any english mistakes.

    A couple of things I think you should check:
    1) Regarding using 200 users and having a queue of thousands of requests... When you say that you have 200 users, this means that you will have maximum 200 threads simultaneously on the client side, right?
    2) What is the read timeout on the client side? That could explain the number of threads in use in weblogic. Threads might be left running, and if the client stops waiting for the response and initiates a new connection, it could lead to the scenario you are describing.
    3) As you said that the web application starts consuming less CPU when the issue happens and at the same time the queue increases, it seems to me that you might have a contention on the webservices. Are you also monitoring the webservices? Do they run in a different server? Is it deployed on the same physical server but in different weblogic server, or it's deployed in the same weblogic server?
    4) Did you run performance test in the webservices on their own to make sure that they scale?
    5) In this situation, I would run a separate performance test against the webservices. Then I would stub the webservices and run a performance test in the web application. By stubbing the webservices, I'm able to create any kind of behaviour I want. E.g: Simulate slow response times, respond under a consistent response time, etc.
    6) Is there a read timeout between the web application and the web service?

  • Hp dm4-2070us cpu usage & fans? help!

    Lately I've been experiencing fan problems and how its really really noisy. I started to notice that the CPU Usage levels were fluctuating high and low. It would start out as 3% go to 9% then 30%, 40%, 70% and eventually 90% and the highest was 99% and then it would go back to 3% and start this process over again. When the CPU Usage goes higher the fans start to become louder. I had just booted my computer and opened firefox and had ONE window opened and the CPU Usage went up to 99% and the fans were INSANELY LOUD. I thought my laptop was going to blackout.
    Is this happening to anyone else? Is there a solution to this? I don't do anything with my laptop like intense gaming or anything. I'm just a student that uses this laptop for word processing, internet browsing, music, instant messaging and a little photo editing. I don't see why my laptop would just suddenly go crazy like that. I just bought this like 2 months ago back in July..
    Help is much appreciated!!

    I also had the 100% CPU usage error on my Pavillion dm4. I verified that no applications were causing the excessive usage and performed a virus scan on my computer while it was running in this state. The BIOS update obtained through HP Support Assistant seems to have fixed the problem. The CPU usage went down when the update was downloaded and installed (before the required system restart). 
    I just recently performed this BIOS update, so I will post again if I find that the problem resurfaces.

  • 10.8.2 Browser CPU Usage

    My MBP 2011 is having some serious issues with CPU usage for both Safari and FireFox. An idle browser will start to consume >100% CPU at a constant rate for no apparent reason whatsoever, and it will continue to do so until I shut it down. I once left the browser open, walked away, and from a full charge, my MBP battery was depleted within the hour, if not sooner. In fact, with FireFox, the CPU usage becomes so intense that I can't barely drag the mouse to the dock to termiante the browser. I reinstalled my OS at one point, and the issue persists.

    All I can suggest is to try chrome. I've used for a few years on PC and on my Mac for the last 14 months with no problems what so ever.
    Of course you could unintstall and reinstall FireFox and test. Not so easy to do with Safari as it is part of the OS and the only way I know of reinstalling is to reinstall the operating system. I have no idea if it can be uninstalled.

  • Excessively High CPU usage on my Equium M70

    HI,
    Recently in the last month my CPU usage as been hitting 100% when Im not running any taxing software (just internet explorer and windows media player).
    This is slowing down loading times and the area near the fan is pretty hot.
    I have an Equium M70-337, with a 1.7 centrino processor, and now 2 gigs of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problem like this, now it's just started happening recently, I haven't installed anything that would do it, there are no unnecessary programs running and this was after I restored my comp to factory settings with the startup disc (about a month after) so it seems to have come from nowhere. On the task manager list it shows my web browser and media player using up the majority of CPU but I could have sworn that they didn't use up this much before.
    I don't know if the RAM would have been a factor but it was the correct ram for it and windows acknowledged to 2 gigs.
    Why would this have happened suddenly, any ideas guys?

    Hi
    I have the same notebook model and at the moment I do not have such problems. To be honest I have made clean OS installation 3 months ago and after Microsoft update installation I have noticed that notebook does not run like before. Just for example: if I use IE7 intensively with several different tabs in task manager I can see that IE need over 300.000 k of memory and somehow blocks. After closing IE and ending the IE process sin task manager I can work normally again.
    I really do not know how is your OS configured but in task manager you should see which running process is responsible for high CPU usage. Maybe some antivir application? Sorry but on this way it is really not easy to sayt why this happen. Play little bit with running processes.

  • Overheating,fan broken, running extremely slow, cpu usage 100%

    whist playing an online game my toshiba laptop suddenly started lagging, it didn't shut down ( as you would expected when a laptop overheats) but the fan has completely stopped working. the cpu usage is at 100%. i've run disk clean-up, defrag , downloaded all my driver up-dates, run anti-virus software. pretty much everything but wiped the computer. will a new fan put the computer back at normal speed?

    Hi,
    Welcome to HP forum. You've posted to a wrong forum from vendor view and from machine view (this is a desktop forum). Anyway we are here to help. Your idea is having a new fan, this may or may not help. The main thing is to keep machine cooler. These are few tips.
