WindowServer eating up CPU; kernel_task eating RAM

Ok well I got two problems firstly one more annoying poblem is that my WindowServer tas is totally eating my processor eventho I just restarted my computer is will quickly start driving the CPU to aorund 60% pretty penently. If I am just trying to trype a message for example on a website with flash it takesthe text ages to appear lag behawfully and even in this forum the text is lagging behind slightly while typing this message. Sometimes it is normal usually when I just restarted but in the case right now not even that seems to have helped.
Then the other problem is that kernel_task seems to be sing a lot of RAM after restart it was str8 on 160MB and then after started firefox and running for about 5 mins it is already using up 323 before I restarted it was using around 600MB is this normal? seems a little much especially when I heard it was only using aroudn 60MB for other people
Hope you guys have some tips for me!

thanks that may well have been the problem, but after defragmenting (iDefrag) this weekend, the problem seems to have gone, i think.
The problem started after clearing all the caches including system caches and i wonder if it was just trying to rebuild some, but the constant "clicking/whirring" sound has stopped and I am abled to run smoothly with several apps/intensive apps going without lag and beachball.
I am not totally sure if the problem has gone so may reset SMC next weekend anyway. It may have also had something to do with Safari but again I'm of course not sure as I am no Apple technician. I thought I would write as much as I could as this is probably a problem that will come up with other users and I could not find much on it.

  • G5 eats RAM

    About 3-4 months ago I began having problems with dual 2.0 G5. The HD went berzerk. I also niticed that I was having RAM problems. This showed up first as kernal problems, then checking the system setup it showed RAM slots empty.
    I ordered and installed a new hardrive, then was able to slavage the old. I also ordered and install 4 1GB RAM cards from OWC. They are PC3200 which is what I took out, and what OWC and Apple said were correct for this machine.
    Trouble free for the past few months, then the other night I noticed that syure enough 2GB of RAM was not showing up.
    I mnoved it to another slot, and imediatley had kernal panics. Now on startup I show 2GB, with empty slots were there is RAM installed.
    Why is my machine eating RAM?

    Hi ilovetrainskc :
    Sounds like either bad RAM sticks or a flakey motherboard/RAM controller.
    Try:
    1) Poweroff, unplug everthing wait 5-10 mins , replug and boot up.
    2) Reset the PRAM/SMU see:
    http://docs.info.apple.com/article.html?artnum=300341
    3) Try reinstalling the RAM sticks in another slot.
    4) Run the Apple Hardware Test on the sytstem DVD that came with your machine.
    5) Do you have the right ram sticks, and are they installed in order and in pairs? see:
    http://docs.info.apple.com/article.html?artnum=86414
    6) ......"They are PC3200 which is what I took out" .... put the original RAM sticks back in as well.
    7) Make sure all RAM sticks are seated properly, i know it is silly and obvious but I've seen it as a problem.

  • Windowserver suddenly hogs cpu with Lightroom and Photoshop

    I recently upgraded these software packages to 64bit and upgraded NIK plugins for each to the 64bit versions. Since then I've had problems with PS freezing while making adjustments using a NIK plugin (doesn't appear to be plug-in specific). Looking at the Activity Monitor I see windowserver up to 90+ cpu usage. Sometimes if I just wait it will recover, sometimes I have to shut everything down.
    Anyone seeing this problem while using this software and if so have you found a remedy? This never happened while using the 32bit versions of all these packages.

    My understanding is that windowserver is an OS X application independent of software used. My question is whether others have seen windowserver start hogging CPU time while this specific software was being used and any Mac remedies that solve the issue. It's not an Adobe question.

  • How to find the current CPU and Memory (RAM) allocation for OMS and Reposit

    Hi There,
    How do I check the CPU and memory (RAM) allocation for the OMS and the Repository database? I'm following the "Oracle Enterprise Manager Grid Control Installation and Configuration Guide 10g Release 5 (10.2.0.5.0)" documentation and it says to ensure the following:
    Table 3-1 CPU and Memory Allocation for Oracle Management Service
    Deployment Size Host CPU/Host Physical Memory (RAM)/Host Total Recommended Space
    Small (100 monitored targets)                   1                                             1 (3 GHz)                            2 GB                                                                        2 GB

  • Performance - Threads - Sys Resources = What's the CPU Speed n RAM ?

    Hi all,
    I am writing a small program based on quick port scanning (pure Java). For that purpose I'm using threads to make the connections. I am using multiple threads in parallel. While running 64 threads theres a 10% CPU usage whereas on 128 threads theres a 60% usage (On AMD 500 Mhz).
    Now obviously I dont want anybody with a 233 Mhz running my program with 128 threads and surely not the one with 1 Ghz being limited to only 128 threads. Thats why I need to find out the clients resources like CPU speed, total RAM etc. How do I do that ?
    Someone suggested using JNDI for windows registry. I'm not sure how to do it that way. (if anyone can provide me a little code?) Is there another way round to this problem?
    Any help appreciated.

    My friend
    please try to understand the problem here is not of OPTIMIZATION OF THREAD SERVICES but the OPTIMAL NUMBER OF THREADS TO BE USED at certain processor speeds.
    fine I agree about different performances of processors (pentium 1Ghz != AMD 1Ghz)
    but surely (pentium 1Ghz ~ AMD 1Ghz ~ other 1Ghz).
    and anyway in my program I'm taking the performance margins by 200Mhz to be on the safer side
    i.e.
    x1-x2 no of threads for say 300-500Mhz,
    y1-y2 no of threads for 500-700Mhz,
    z1-z2 no of threads for 700-1Ghz. Get the point.?

  • Question CPU speed VS RAM speed

    I am tweaking my new worstation.
    I have an Asus p6t ws professional. I7 960
    24 G DDR3 tripple channel ram (Patriot Level 7 Viper II)
    I am new to overclocking and I up to now I don't know how to solve this propblem.
    If I overclock the CPU by putting the BCLK frenquency to 160, with default multiplier at 25, I clock 4.07
    But, when I check the speed of my RAM with CPU-Z, I get a clock of 490 (!!!) so time two 980 (not even the 533 x2 to 1066)
    If I put my bios to XMP mode I get my ram to 1600, but my cpu is about 3.4 (close to normal 3.2)
    How can I OC to 4.0 with 24 G RAM at 1600?
    The mother board manual say it acccept 1600 RAM but (OC) And THEY SAY THAT iNTEL SPECIFICATION, IN xmp mode, DDR3-1600 are supported for one DIMM per channel only (does that mean I cn only put 16 gig in channel A,B and C If I want 1600 OR 24G butr at a lower clock around 1066?
    IF I am stucked in making choices and can't have it all (CPU 4.0 and 24D RAM-1600), WICH IS THE MOST IMPORTANT: CPU SPEED OR RAM SPEED?
    I mostly edit P2 and wil be editing red and filmstock transfered.

    Using a Gigabyte MB and cooling with water my i7-950 is rock stable at 4.3 with 24GB of 1600 G Skill RAM running at 1624; I have CPU turbo disabled and RAM XMP enabled and running at 1.5 volts.
    Based on my clocks (BCLK 203, CPU 21, turbo off, QPI 36, MEM 8, and Uncore 16), I would suggest trying the following to reach 4.0 with your 1600 rated RAM:
    BCLK 190
    CPU 21
    turbo off
    QPI 36
    MEM 8
    Uncore 16
    If that is not stable for your Asus, Try lowering BCLK until go get something that is. These settings would put your RAM at 1520 which would certainly be close to their maximum potential.
    OC'ing can be time consuming; if this "formula" does not work for your system, then you really do need to go with the tried and true methodical approach.
    Regarding which is more important for PPro I would say CPU speed is much more significant than RAM speed based on runs that  making with Harm and Bill's ever so useful PPBM5 benchmark along my journey.
    On another note, Cristobal on this forum informed me about "INTELBURN TEST" (Google it), which was a more rigerous torture test for stability than the ones that most people use (memtest, 3DMark, wPrime, etc.).
    Good luck and do report back what works best for you in the end; it would be nice to report how your drives are set up too along with your PPBM5 results as well.

    Because I have a Problem with my CPU: Kernel_task and corestoraged.

    I'm having this same issue. I also have this line in my log, which is curious:

  • Slow, eating RAM and CPU

    Lately, Safari is being a real resource hog.
    ProcID / Name / User / %CPU / # Threads / Real Memory / Virtual Memory
    499 Safari beavis2084 67.40 9 113.92 MB 360.99 MB
    Weird... anyone have any clue as to why this would occur recently ?
    Beavis2084

    Not a recent issue. There are definitely "world leaks" occurring, which not only create higher RAM requirements, but also slow down connections to sites or navigation within the sites. My temporary remedy is to use Activity Monitor to keep track of Safari. Once it exceeds 250 mb RAM, I restart it. Other alternative is using Firefox.
    A search of the forum using "safari slow" produces over 100 posts of mostly complaints.
    I've sent a "bug report" to Apple. I suggest you let Apple know too.

  • Mail eats RAM

    Every time I fire up Mail it eats up all my memory.  I can see it climb up in the list of the Activity Monitor, eventually to use up everything. Other applications lock up and I have to force quit everything if I don't force quit Mail first.
    I've set all mail options that I can think of to "off line", set a seldom used "dummy" email account so that I know there aren't many messages that might have to be retreived but it still happens every time.
    I do all my emails on line via ATT/Yahoo, but I'd like to use Mail to compose custom emails and easily embed images (get with the program, Yahoo!).

    Hi,
    How can rebuilding your mailbox help when all mailboxes were offline and still the memory was filled?? It is also happening to me for the past 2 weeks...
    Greetings,

  • X is eating RAM

    Hi. I've noticed that after some hours using KDE 4.5.1 the process X uses a lot of ram (now is on 400 MB).
    I don't know exactly what information do you need to help me, so I will post the KDE's Monitor (ksysguard) detailed memory information about X. If you need anything else, please tell me.
    Process 20722 - X
    Summary
    The process X (with pid 20722) is using approximately 411.1 MB of memory.
    It is using 409.2 MB privately, and a further 3.9 MB that is, or could be, shared with other programs.
    Dividing up the shared memory between all the processes sharing that memory we get a reduced shared memory usage of 1878.0 KB. Adding that to the private usage, we get the above mentioned total memory footprint of 411.1 MB.
    Library Usage
    The memory usage of a process is found by adding up the memory usage of each of its libraries, plus the process's own heap, stack and any other mappings.

  • Flash Player eats RAM

    Nice job guys.
    Flash player, when viewing a video, consumes RAM at a
    ferocious rate.
    It continues to do so as long as the video is playing. If you
    watch the same video twice without closing it, it will suck twice
    as much memory.
    Watch long enough without closing, your machine will
    evenutally start thrashing the page file and ultimately crash.
    Heh Adobe, this is 2007. You do know how to make a "free()"
    call when you're done with a "malloc()'d" block of RAM, right?
    Flash player is pretty much REQUIRED nowdays for most web
    sites. This is blowing up people left and right that are trying to
    view my Camtasia videos - I'm fixing to tell the Mac Users and
    Adobe users to get screwed and start pushing WMV files instead, and
    of course I will be more than happy to capture a screen shot of my
    Windows XP diag console showing my system RAM being sucked dry by
    your player with a VERY LOUD FLAME on my web pages, advising people
    NOT to buy or use your products.
    Get real.

    It shows Peter's doing its jobs properly.
    Anyway there is no more communication from Sony since awihle. If you can have any news.
    Anyway good job Zero!

  • Themes eating ram?

    do themes use up loads of ram? i didnt think they did at all

    I guess it depends on how the theme is with pictures, amounts of icons, effects etc. I don't know what phone you got, but maybe you could use a taskmanager and check with different themes, if there are any signicant difference in usage of ram after reboot for example. Usually it shouldn't be a big issue. If you're looking for themes at certain sites as zedge you will find tons of good themes and tons of more or less bad themes. Try some you like and see if there are any that suits you.

  • PreferenceSyncClient eating RAM and taking minutes to run

    Every hour on the hour, PreferenceSyncClient proceeds to take up 1+ GB of RAM (out of 4) while bringing my machine to a near standstill. I must force quit it in order to get in work done in the next 10 minutes. I am not a .Mac subscriber. I've looked at Syncrospector and it shows nothing out of the ordinary other than trying to Sync the Preferences with something. I've removed almost all 3rd party preference panes (except MS Mouse, Keyboard and MySQL which have all been around for a long time before this problem started occurring.) Also, note, it does this regardless of whether I've changed any preferences or not.
    Anyone have any insight on how to deal with this? Can I just rename/remove the PreferenceSyncClient.app? Or, perhaps, I should edit the sync plist and remove the server synchronization part of it (not that I know what server it is syncing to).
    Thanks in advance,
    Grant

    I ran into trouble with SyncServices going back to 10.5.0-10.5.3, in my case I noticed it using Tri-Backup 5 along with Disk Warrior, that something wasn't right and was in the sub-folder "local" I believe, which looked like spaghetti string - alias files that I couldn't make head or tail.
    I think your fix is easier and more elegant!

  • Kernel_task high RAM usage

    Hi everybody,
    I have same problem on both iMacs i use (iMac9,1 and iMac10,1). Both updated from Maveriks to Yosemite some months ago and since last 2 weeks kernel_task "eat" to much RAM.
    I tried to solve with all kind of resets, move files from ACPI_SMC _PlatformPlugin.kext, hardware test, reinstall and restore from time machine and finaly also with a complete clean reinstall (without TM restore!). But kernel_task run with too much RAM usage.
    I feel frustrated and I seem to be back like Windows users!
    So, i think problem could be associated to some software upgrade (DropBox? Skype? Osx update? don't know). Anyone knows if there are usefull debugs system log for kernel_task usage?

    On this report kernel_task ram is not displayed but you can see it on task manager image
    Any help is apreciated.
    Thank you!

    There is nothing wrong with your kernel_task memory usage.  It is consistent with the amount of RAM you have installed.
    The kernel_task manages virtual memory page tables.  The more RAM the the more table space consumed.  800MB memory usage for kernel_task is in line with having 8GB of RAM in your Mac.
    My 16GB Macbook Pro kernel_task has 1.15GB of memory.  People with 32GB Macs, have more like 1.5GB.  And Macs with 4GB have something around 500MB more or less.
    Tangent observation.  Unless you have a Paid LogMeIn account, the free version has been discontinued, and you should most likely remove the LogMeIn components via the LogMeIn uninstaller.  Your use of TeamViewer.com is a good substitute for the free LogMeIn.
    You system has been up for just 7 and a half hours
        OS X 10.10.2 (14C109) - Time since boot: 7:21:25
    But you have
        117.96 GB    Page-ins
    That averages out to 4.6MB per second.
    Chances are you could either benefit from not running as many concurrent things (maybe remove the large number of kernel extensions, launch daemons, launch agents you have installed), maybe only run VirtualBox when you really need to run Windows (assuming it is Windows, but I guess it could be Linux or Solaris X86), or have fewer tabs open in your web browser, or run fewer Apps, especially the big memory hungry kind)
    Or maybe you just need more RAM if you must have all these things installed and running all the time.
    Just a thought.  But it is not kernel_task that is causing problems.  That is normal.

  • CPU kernel_task Usage Rendering MacBook Pro Unresponsive

    For about a month I’ve been having issues with my office setup when docking/undocking my 15-inch 2012 MacBook Pro. As soon as I launch a couple of applications (Adobe Muse, Photoshop, Parallels, etc.) kernel_task begins eating up all the CPU threads, rendering the MBP unresponsive and nearly inoperable. I have been using my dasiy chain setup for over a year w/out issue prior to a month ago.
    Steps I’ve taken to resolve the problem:
    Resetting PRAM
    Resetting SMC
    Disconnecting Peripherals
    Results from the steps seem to work for a little while, then the problem returns.  The one caveat to that is – the kerenal_task ramps up CPU even when all peripherals are disconnected.  I’ve been cautious of contacting Apple Support for assistance, as I’ve been unable to replicate the issue on demand. kernel_task just happens, and happens right in the middle of me doing something important.  This makes me believe my hardware has become faulty or I’ve recently installed some software that is affecting the functionality of the MBP.  Which isn’t a huge deal, I just want to resolve/pinpoint my issue so I can address it.
    In researching the problem I’ve found the following threads that I believe are similar to what I’m experiencing.  Posts by Linc Davis have been extremely helpful, I just can’t seem to put a finger on my specific problem:
    https://discussions.apple.com/message/22529264#22529264
    https://discussions.apple.com/thread/4817768?start=0&tstart=0
    Any and all suggestions/assistance would be greatly appreciated.
    Note: Set up – MBP > Thunderbolt Display > Seagate GoFlex Desk Thunderbolt Adapter w/ HD attached > 2005 20” Cinema Display.

    Preface:
    I had iStat Menus installed and it seems this was the root cause of the kernel_task issues I was experiencing.
    After taking the Thunderbolt display and MacBook Pro to the "Geniuses" to verify that the issue(s) were not being caused by my hardware, it boiled down to pinpointing a software inconsistency.  A post made by Linc Davis helped me start the digging.  He mentioned in one of his post that:
    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.
    I tried uninstalling the software to see if that would solve my problem.  Unfortunately it didn’t; therefore, I went about making a full Time Machine backup, a system clone using Carbon Copy Cloner, and reformatting and reinstalling OS X.  This may not be the ideal fix for some of you, but fortunately I maintain many backups.
    For me, that solved my problem!  The kernel_task hasn’t shown up for over a month and everything is running extremely smooth.
    Note: This is really not desirable for the majority of you, as it is highly time consuming and may not be practical for you, but it is definitely a surefire way to solve this problem.  I didn’t restore from any of my backups, I only made backups for a “just in case” instance.  I decided to do a fresh install and set up my system from scratch.  I maintain all my software DMGs and serial numbers on a separate HD which made this a smooth way for me to go about restoring my workflow.
