MY CPU is extera slow

I (have) a 06' iMac (and another one same model, even more memory taken up at a different house is not doing this) that has 131 GB free and has been extera slow in the last 4 months help!!!!!

What size hard drive do you have & how much free/available space. An almost full hard drive along with your somewhat small amount of RAM can cause slowness.
Your Mac needs adequate hard drive space to operate normally. How full can a drive be before it's too full? There is no hard and fast rule that says “X” amount or “%” of free drive space is needed. A low amount of RAM requires more drive space for Virtual Memory’s swap files. Problems from insufficient RAM and free hard disk space are discussed in this link

  • CPU and GPU slow down after system upgrade

    Ok, I can't find anything similar to the question I have...but this forum goes on forever  
    As my system specs appear below, my machine was running quite comfortably a week ago, with same setup...minus the acrylic case and second 120GB hard drive.
    At that stage I had "nomal" benchmarking scores 3dmark03 - 5850, Aquamark3 41.000, PC mark 2002 - cpu7020 mem8438 hdd1050.
    Life was good and I loved my system
    Then I decided it would be cool to upgrade to an acrylic case (which has better cooling with 3 fans) and a second 120 GB HDD to make a striped raid array.
    My first concern was the raid Array. I was carefull to buy the exact same seagate hard drive, size etc. the original was only a month old anyway. The second was to use the intel southbridge chip for SATA RAID or the Promise controller? After researching these forums I decided to go with the Intel as it has more possible bandwidth and doesn't sit on the PCI bus.
    I got the new case and wearing those stupid white gloves, proceeded to move the components over and trash my "old" metal case.
    The windows NTFS format (full) flew by in 30 seconds and I was really impressed.
    Once windows xp and all it's drivers and updates were installed, incl sound and graphics etc. I did a 3Dmark 2001 test before upgrading to Dx9...what a bad mark! 3Dmark2001SE - 9950 (terrible for this system).
    I thought it was a DX problem...so I installed Dx9
    Then opened that corecenter program (the old one, the one that doesn't crash...)
    and my CPU was about 5c hotter than usual, it was running at 40-42c (I have standard intel cooling fan). It went up to 55 at times when running PC mark 2002.
    This didn't concern me too much a the system was stable at 32-34c and the northbridge read 60c (but we all know that's not true , more like 35ish.
    My PC mark 2002 is now cpu4200 - mem4800 - hdd1800
    (at least the HDD improved!) LOL
    I ran Aquamark3 next...29,900 (ouch!)
    Previously my CPU was 8,700 and GPU was 5300
    now the CPU read 4400 and the GPU 4600
    I don't really notice the speed loss when working, but games and benchmarks tell a different story.
    So, My question: What has happened? Why is my CPU power cut in half? and the graphics card slightly slower? The memory speed stayed the same and the HDD speed improved....not a worthwhile upgrade IMO
    What went wrong?
    Here are my theories.
    1) The CPU and system case is getting too hot
     Does the CPU "throttle" when it overheats? this could be the reason.
    Also both HDD get really hot and the fan in front blows air over them, this hot air could be going over the CPU or GPU. Maybe get 2 HDD coolers?
    should I buy a better CPU cooler like the Thermaltake spark7+ ?
    2) The PSU does not have enough watts
    I couldn't find traces of voltage lack or spikes...but it could still be a problem
    3) The RAID0 array is a strain on the CPU and chipset
      I'm not sure about this.
    My appologies for the lengthy thread, but I wanted to be sure that anyone trying to figure this out had as much info as possible  
    Thanks if u can help me figure this out.

    Perhaps I should upgrade the overall cooling. Get a Thermaltake copper fan and two HDD coolers.
    Well, your temps sound allright, no need to worry them, if they really operate at that level.

    The solution to set the FSB to 201Mhz sounds good. But do I set this in the BIOS or with Corecenter in windoze?
    Propably meant to adust your FSB at BIOS, at least that is what I would suggest.

    I will try to re-install the VGA drivers because something strange DID happen when I first installed them. I started with the hercules driver CD, this installed CAT 3.2 drivers. I then upgraded to CAT 3.7 and before it completed I got an error window (send, dont send).
    Remove drivers AND ATI control panel first, and then re-install. Use drivers from ATI site, and rather Catalyst 3.7. I Have had problems with 3.8 Catalysts.

    Still wouldn't explain why the CPU seems so crippled. I have managed to get a "normal cpu score of 7000+ in PCmark2002 by shutting down, restarting later and killing every process except explorer.
    Do you have any processes that seem to eat more juice thant hey should?  Arrange your processes by CPU usage and see if there is something strange.

    If this cant be fixed I will reinstall over the weekend. Does anyone know of the RAID0 array on the southbridge causing a system slowdown?
    I'm using Intel RAID and it works perfectly, no extra CPU usage is shown and it's pleasantly fast!
    And Install latest Intel INF updates and Application Accelerator from Intel site. That's what I'm using, and works fine.

  • Qosmio G55 CPU's running slow on Vista 64 and Win 7 (64), no hardware or software problems found

    I have what I believe is a hardware problem causing slow cpu clocking and 100% cpu utilization, even though the processors and hardware check out okay and I can't find any performance problems other than the slow cpu's. Any ideas where else to look, aside from what's listed below?
    A few weeks ago, my Qosmio G55-804 on Vista 64 SP2 suddenly became very slow. In Task Manager and sysinternals procexp64, both cpu's stayed at nearly 100% all the time. I stay current on patches, updates, drivers, anti-virus, BIOS (2.30), do regular full malware scans and defrags, and use a dedicated 8GB SSD contiguous pagefile. I upgraded to Win 7 (64) SP1, and rechecked all drivers, but the problem remained. Using Windows Performance Toolkit 7.1, I was unable to locate any cpu hogs or other performance problems.
    The device manager shows all devices working okay. The BIOS debug test passed all hardware, as did the Windows Memory Diagnostic, and Toshiba PC Diag. The Intel Processor Diagnostic Tool passed both CPU's on all tests.
    However, HWINFO64 showed that both CPU's were running at only 1/4 to 1/3 of their rated 2 GHz speed. The Windows Experience score dropped from 4.3 to 1.2. The BIOS processor clocking is set to ALWAYS HIGH, as are the power plans.

    I ran an analysis of my system with AIDA64 Extreme (attached). It gives a fairly complete description of hardware, firmware, drivers, OS, etc. It's somewhat of a "too much information" problem. I may have everything needed to identify the problem, but I don't think I'd know if if I saw it.

  • Media Encoder only using 15% CPU, and system slows to cement

    Not sure what's going on, but trying to export from Premiere CS6 to Media Encoder and very basic 640x360 H264 4 minute clips are taking 40 minutes, only using 15-30% CPU (on 2011 Macbook Pro 2.3 core i7), and the system slows to a cement crawl (had to stop it just to type this post). Nothing else is using any CPU and RAM is 25% free.
    I don't even know where to begin to troubleshoot. Tried restarting is all so far. Any advice would be greatly appreciated.
    Thanks,
    Brandon

    It seems there is a problem with the Mercury Playback Engine on my MBP. I turned it off and switched to software only mode, and now CPU is screaming at 750% on export and estimated time is about 8 times faster

  • NB205 - Weird CPU usage, very slow even after system reinstall.

    Hello dear Forum,
    I have a problem with my Toshiba NB205, the CPU usage while moving; dragging for ex. an explorer window, jumps to almost 30% and it lags pretty much (which I guess is not pretty normal) also while watching a YouTube video (360p) on full screen the frame rate is not higher than 5.
    I have a fresh Windows 7 Starter system installed on it, I moved from Windows XP because of the Weelsof virus that attacked the computer, but even before the attack it was very slow, it took very long to open a folder window.
    I formatted the all the partitions (including System Reserved) except the "HDD-Recovery".
    I am not owner, nor the main user of this laptop, so I don't when it became so slow, but as far as I remember it worked perfect at the beginning without any bigger problems.
    Thank You for Your help

    Which NB205? See the label on the bottom.

  • MSI K8N Neo 4 CPU cooler is slowing down ?!

    Hi everyone and HAPPY NEW YEAR TO ALL AND ALL THE BEST!!!
    I have brand new MSI K8N Neo 4 mobo and something strange is going on. CPU cooler on Venice 3000+ s939 in BIOS is rotating on 2200 RPM, but when i start Win XP, Core center and Everest are showing only 1000 RPM.  Cool'n'quiet is disabled in bios.
    Is there some setting that  I did'nt see or what?
    Thanks for your help in advance.
    Pufta.

    Hi!
    Thanks Hodgie_ns for your fast reply, but it was not set up in Core Center for Cool'n'quit to slow down, it was on user setting to maximum.
    Problem resolved by connecting the CPU cooler on the other connector for SYS FAN for little time, then I connected back to the CPU FAN connector. Since then, it is working on 3000 RPM all the time. Funny?! Wird?! Bug?!
    Thanks and go for it!

  • IMac (late 2009) CPU runs very slow (about half speed)

    After having had troubles with performance I 've recently discovered, that Geekbench as well as Xbench return results way too low for my machine. In fact it appears results are exactly half the speed one would expect. In Xbench CPU power is about a score of 110 where I had 220 with 10.6 for example.
    Now I had done an SSD update a couple of month back and this speed gain probably masked the CPU problem. I might even have damaged the small monitor synch cable during the procedure but all hardware tests (TechTool Pro 6 for example)  show no problems. 
    I've tried resetting PRAM and SMC but to no avail. Also booting into SAVE Mode did not change the behavior. Here is my etre check profile:

    Somebody posted a very similar problem, resetting SMC helped there. Running Bench I can see normal degradation when running other tasks (i.e. from 110 CPU which is max of what I can get at the moment to 80-90 when running other apps) So it really seems to be some preset which keeps the CPU from running both cores or such.

  • Xorg using 30% cpu when idle,slow performance and video problems

    I'm having a problem with Xorg, I don't know what it is but I guess it has something to do with configuration problems because in Ubuntu eerything works out of the box.
    My problems are these:
    1. Xorg is using arround 30% cpu when the computer is idle and very simple animations in kde like minimize a window are performed very poorly.
    2. Compiz' performance is very poor and chopy
    3. h264 videos are not wachable. it feels like watching 3fps videos.

  • A55M-P33, CPU fan not slowing down with Cool&Quiet

    Hi,
    I recently build a computer with an A55M-P33 motherboard and A4-3400 CPU with stock fan. That CPU came from my computer and was working fine, the fan too and both throttled down with Cool&Quiet enabled.
    On the A55M-P33, the CPU does throttle down (checked with CPU-Z), but the CPU-fan does not. It keeps spinning at full speed.
    Did I miss a setting in the BIOS, besides the setting to enable Cool&Quiet, or is there something else going on? It's not a big issue though, just a little bit of extra noise, but I hate it when something does not work as it should.

    Only solution to that is to determine if you even need the case fan. If you do, then perhaps you can parallel the case fan with the CPU fan if its PWM, else, look at an aftermarket fan controller.
    Example http://www.sunbeamtech.com/PRODUCTS/Rheosmart/3.html
    and  http://www.amazon.com/Sunbeamtech-PL-RS-PCI-Rheosmart-PCI-Controller/dp/B004LL8KF6/ref=sr_1_1?ie=UTF8&qid=1380284728&sr=8-1&keywords=rheosmart

    I am running a Finite element commercial solver, our tipical installations are with windows server 2008 but now we were force to move to windows server 2012.
    When we launch the solver, which may be working with up to 20 cores, the CPU usage remains consistent for about 40 minute/1 hour then drops to the usage of only one core without having completed the process, which complete several hours later.
    We already tried putting the power management at High performance, but didn't solve.
    Are there any suggestion regarding where to look at?
    Thanks 
    Raffaello

    Hi,
    First, please make sure your hardware support windows server 2012. I’m not sure what “Finite element commercial solver” is. So I just treat it as a kind of software. Is there
    any compatibility with the software with the new OS?
    Process Monitor may help address the issue.

    Hope this helps.

  • ITunes uses almost 100% of CPU and slows PC down

    Recently I decided to start using my iPod touch 4G again and downloaded the latest version of iTunes.
    Upon launch, iTunes acts normally until about 4-5 minutes of being open (just in idle). It then happily proceeds to use up 100% of my CPU load and slows my entire PC down to a halt, even once I've closed it (iTunes).
    I've tried re-installing it, downloading a different version, disconnecting from the internet, practically everything and yet the problem persists.
    My PC specs are as follows:
    Amd FX Piledriver 8-Core FX-8350 @ 4.0GHz
    Powercolour HD7990 Devil 13
    G-Skill 1866Mhz 16Gb memory
    OCZ Vector 128Gb HDD / WD Caviar Green 3TB
    So I can assure you, this is NOT hardware related.
    I've tried the following method with no results.
    1) Click Start and type "cmd" (without the quotes) DO NOT press enter or Ok yet.
    2) Right click "cmd" in the search results at the top of the start menu and select "Run as Administrator".
    3) In the command window, type "netsh" and press enter. (Without the quotes)
    4) In the next prompt, type "winsock" and press enter. (Without the quotes)
    5) In the next prompt, type "reset" and press enter. (Without the quotes)
    6) Reboot the PC. (Do not skip this step)
    I've also been through the list of conflicting software and have none of the mentioned.
    I'm running Windows 7 with the latest updates.
    I'm getting extremely frustrated now. ANY help would be appreciated.

    Sorry. I did a search, and a lot of threads came up. The one I chose, I thought, explained WHY it happened.
    Maybe you'd get answers more helpful to you, if you went throught the search results.
    Sorry I wasn't of any assistance.

  • X-Fi + 2 GFX-Cards = high CPU-Load, slow Mouse, hanging system

    >X-Fi + 2 GFX-Cards = high CPU-Load, slow Mouse, hanging systemA Hey guys,
    I'm running 2 GF 8800 GTs (PCIe .) cards on a MSI Eclipse SLI board. My Audigy2 ZS PCI runned fine in this system.
    I just replaced the Audigy by a PCIe X-Fi (EMU20K2 audio processor - not the xtreme audio from MSI).
    Now I'm dealing with the following issue:
    - System startup is slow
    - in Windows, Mouse is slow, stuttering
    - high CPU-Load
    - very slow system response
    !!! Attention !!! I had this problems allready at the st boot with the X-Fi, when the driver from creative wasn't installed (the card was recognized as "HD Audio" bei Windows 7). Installing the drivers didn't help.
    If I install only one graphics card, the system runns fine and I can use the X-Fi and it's Software without problems.
    If I replace the X-Fi by the PCIe Xtreme Audio from MSI, System runns fine.
    If I use Win XP with the two GFX cards and the X-Fi, System runns fine.
    Can you help me?

    User....

    Hi there,
    got the same problem if i use my two Nvidia GTX260.
    My system:
    Asus P6T
    I7 920 @ 3,8GHz
    2GB ram
    Gigabyte GTX260 OC Edition
    Nvidia GTX260
    X-Fi XtremeGamer
    -System (Win7x64) takes ~0min to start.
    -Stuttering mouse, keyboard everything >.<
    Deactivating the onboard sound doesnt help.
    Newest Nvidia and Creative driver too =(
    The system runs fine without the X-FI and two GTX260 no errors ect...
    One GTX260 runs also fine with the X-FI
    But two graphic cards and the X-FI..... **bleep** =/
    I use debian as my main OS and it run still fine with both graphic cards and the x-fi...
    so i think its just a driver problem.
    Hope it will be fixed soon =/
    If someone have any sugestions...please help us.
    Greetings from Germany also =D

    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%.

  • DW FTP is slow and causes CPU Spike

    Does anyone know why DW causes the CPU to jump up when it is
    performing FTP operations? I'm new to DW and maybe this is normal,
    but it shouldn't be. When I perfrom FTP activities, DW usually
    takes up about 60-70% of the CPU???
    Also, why is the FTP client so slow?
    Dreamweaver takes so much longer than other FTP clients. I
    compared it's usage to SmartFTP, FileZilla, and Windows built in
    FTP, and Dreamweaver is so slow on a magnitude of 20x - 30x. For a
    quick test I tried to pull down a directory using dreamweaver. I
    have all the files local already, so I told DW not to overwrite the
    files...so you would think it should speed through all the files
    and realize that they are all dups and not download anything, for a
    directory with 15 files in it, i would think this FTP operation
    should take about 2 seconds. but it takes dreamweaver about 4
    minutes to complete this, all my other FTP clients can figure this
    out in under 5 seconds, and they don't need to spike the CPU to do
    it.
    A quick search on the web tells me that I am not the only
    person with these problems.
    I really hope Adobe plans on fixing the FTP problems.
    Technical details:
    Dreamweaver CS3.
    Windows Vista SP1, 4GB ram, Fujitsu T4220

    I've had a related, ongoing problem with CS3 running up the
    CPU and acting
    slow for just about every operation for no apparent reason.
    It goes in
    surges, and just acts like molasses half the time, very
    annoying. It is to
    the point that I really don't use CS3, I use DW8, but try to
    use CS3 here
    and again to see if it has started working or if there is
    some patch
    released. This is on my XP workstation at work, and my Vista
    workstation at
    home. Both systems run CS3 slow enough that I just don't use
    CS3. This has
    been going on for over a year, since I got my copy of CS3.
    Too bad really, because I am tasked with approving CS3 for
    use by the rest
    of our WEB team and I haven't been able to do that, so we
    continue to use
    DW8. We are missing out on Spry integration and are slowly
    switching over
    to Eclipse and Aptana instead. I think that if the CPU bug
    isn't fixed, CS3
    will be the version that has us switch away entirely. The
    only hope seems to
    be if they release the next version of DW before we can
    completely switch
    away. We are a smallish state agency and only have 8 DW
    licenses, but
    that's seven licenses they missed out on the upgrade path
    with unless this
    is fixed (mine is the only upgraded so far). It just isn't
    useable in its
    present state. :-\

  • Performance issue with high CPU and IO

    Hi guys,
    I am encountering huge user response time on a production system and I don’t know how to solve it.
    Doing some extra tests and using the instrumentation that we have in the code we concluded that the DB is the bottleneck.
    We generated some AWR reports and noticed the CPU was in top wait events. Also noticed that in a random manner some simple sql take a long time to execute. We activated the sql trace on the system and noticed that for very simple SQLs (unique index access on one table) we have huge exec times. 9s
    In the trace file the huge time we had it in fetch area: 9.1s cpu and elapsed 9.2.
    And no or very small waits for this specific SQL.
    it seems like the bottle neck is on the CPU but at that point there were very few processes running on the DB. Why can we have such a big cpu wait on a simple select? This is a machine with 128 cores. We have quicker responses on machines smaller/busier than this.
    We noticed that we had a huge db_cache_size (12G) and after we scale it down we noticed some improvements but not enough. How can I prove that there is a link between high CPU and big cache_size? (there was not wait involved in SQL execution). what can we do in the case we need big DB cache size?
    The second issue is that I tried to execute an sql on a big table (FTS on a big table. no join). Again on that smaller machine it runs in 30 seconds and on this machine it runs in 1038 seconds.
    Also generated a trace for this SQL on the problematic machine:
    call     count       cpu    elapsed       disk      query    current        rows
    Parse        1      0.00       0.00          0          0          0           0
    Execute      1      0.00       0.00          0          0          0           0
    Fetch        1    402.08    1038.31    1842916    6174343          0           1
    total        3    402.08    1038.32    1842916    6174343          0           1
      db file sequential read                     12419        0.21         40.02
      i/o slave wait                             135475        0.51        613.03
      db file scattered read                     135475        0.52        675.15
      log file switch completion                      5        0.06          0.18
      latch: In memory undo latch                     6        0.00          0.00
      latch: object queue header operation            1        0.00          0.00
    ********************************************************************************The high CPU is present here also but here I have huge wait on db file scattered read.
    Looking at the session with the select the AWG_wait for db scattered read was 0.5. on the other machine it is like 0.07.
    I though this is an IO issue. I did some IO tests at SO level and it seems like the read and writes operation are very fast…much faster than the machine that has the awg_wait smaller. Why the difference in waits?
    One difference between these two DBs is that the problem one has the db block size = 16k and the other one has 8k.
    I received some reports done at OS level on CPU and IO usage on the problematic machine (in normal operations). It seems like the CPU is very used and the IO stays very low.
    On the other machine, the smaller and the faster one, it is other way around.
    What is the problem here? How can I test further? Can I link the high CPU to low/slow IO?
    we have 10G on sun os with ASM.
    Thanks in advance.

    Yes, there are many things you can and should do to isolate this. But first check MOS Poor Performance With Oracle9i and 10g Releases When Using Dynamic Intimate Shared Memory (DISM) [ID 1018855.1] isn't messing you up to start.
    Also, be sure and post exact patch levels for both Oracle and OS.
    Be sure and check all your I/O settings and see what MOS has to say about those.
    Are you using ASSM? See Long running update
    Since it got a little better with shrinking the SGA size, that might indicate (wild speculation here, something like) one of the problems is simply too much thrashing within the SGA, as oracle decides "small" objects being full scanned in memory is faster than range scans (or whatever) from disk, overloading the cpu, not allowing the cpu to ask for other full scans from I/O. Possibly made worse by row level locking, or some other app issue that just does too much cpu.
    You probably have more than one thing wrong. High fetch count might mean you need to adjust the array size on the clients.
    Now that that is all out of the way, if you still haven't found the problem, go through http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
    Edit: Oh, see Solaris 10 memory management conflicts with Automatic PGA Memory Management [ID 460424.1] too.
