High CPU usage and slow response

    High CPU usage and slow response

    Hi everyone. (cross posted from public.backoffice.smallbiz)

    Contrary to my quote and recommendations, my client has purchased a system
    with an Intel Desktop mobo (DQ45CB/DQ45EK) and SBS2008 SP2 and handed them
    over to be used as his 'server'.

    It had RAID1 configured on the board (2 x 1Tb drives) and a single 320Gb
    drive which the shop configured as the system/boot drive (I don't understand
    why you wouldn't RAID the system/boot drive too!?), core 2 quad and 4Gb RAM.

    Anyway, I have re-configured the RAID array as the system/boot drive and
    installed SBS on a 100Gb primary partition. (The 320Gb drive will now be
    one
    of the backup repositories.)



    It runs like a slug.

    Before I installed the Intel ICH driver and disabled SMART it took almost
    half and hour to boot, now thankfully it only takes 6 minutes to get to the
    login prompt.

    Once logged in doing anything takes an impossibly long time.

    I have been watching it for a while now, and with nothing special running,
    the task manager process is floating between 17 and 20% consistently, the
    server manager MMC spikes to 25% for a longer than normal period of time and
    other random processes, WMIPRVSE.exe, SQLServr.exe, svchost.exe and a few
    others, jump to 25% usage or more, pushing the CPU to 100% for extended
    periods.

    It seems to have settled a bit as I write, System Idle is getting 70-80%
    (task manager takes the balance) but it still takes an eternity to do
    anything.

    The installation (both times - I wasn't happy with the initial install) was
    default, follow the prompts, answer the questions. The only thing I did
    extra was to allow Forefront - the trial of AV - to install. Was that where
    I went wrong?

    I understand that Intel don't by default have any drivers available for the
    Desktop board for SBS 2008, and while I only skimmed the HCL, I didn't see
    any Intel Desktop board listed, I do believe that the individual components
    do have the appropriate drivers handy, the video card, network adapter, RAID
    controller to name a few. The only one I didn't find was the SMBus
    Controller for the Q45 chipset for SBS2008.

    Have I stuffed up anywhere? Can I revive the 'server'? Does anyone have
    any idea why CPU usage would be so high when it is apparently doing nothing?
    Should I perform a WU (or would that be a waste of time and bandwidth?)

    Any suggestions or replies will be seriously considered.

    Cheers.

    Re: High CPU usage and slow response

    I have a test box at home running off an Intel desktop board with a
    single hard drive and 4 gigs of ram. It is a bit of a slug and it has
    no AV or overhead of raid.If I were to expect this to work in a
    production environment I would be a fool to run it with anything less
    than 8 gigs. Once you get your box up to 8 gigs you can start to
    wonder what else you can do.

    Are the hard drives server grade hard drives with 16-32 megs of cache?

    If you have experience with SBS 2008 you should be able to state "I
    have installed X SBS 2008 using an Intel 3xxx motherboard with a Xeon
    3xxx processor with 8 gigs of ram and WD server grade SATA drives and
    my customers have been happy with the performance. Would you like to
    have your server set up properly with a proper motherboard, processor,
    hard drives and case?" I have delivered a small number of SBS 2008
    using 8 gigs, a 3xxx motherboard, 3xxx processor, on board raid1 and
    SATA server hard drives with great results. For bigger accounts they
    get SAS drives and a dedicated SAS controller.

    Re: High CPU usage and slow response

    FWIW I upped the RAM on my home SBS 2008 from 4 to 6 GB because it was
    intolerably slow, and that's just a test server that usually runs with no
    client PCs. That's on "real" server hardware, although I doubt using a
    desktop motherboard is a big part of Andrew's problems.

    In my experience with Intel desktop boards, you can sometimes find good
    drivers by seeing the exact component name that's acting up in Device
    Manager, then searching the Intel support forums. Someone in there may have
    figured out a way to make that component work with a different driver -
    probably Vista 64-bit drivers will work - I'm not sure the Intel chipset
    driver installer will work on Server, but if not, you can extract the driver
    files and manually upgrade/install the drivers for the individual components
    in Device Manager.

    I would definitely run MU to get this machine up to date with patches.

    That Intel controller rocks for desktop RAID (I've actually got it running
    on this PC). On a desktop, it does effect drive I/O a little, but IMO not
    noticeably. I'm running it with RAID 1 here and single drive at home, and
    cannot see any difference other than that the WEI for drive performance is a
    little better on the single drive system. Of course, the minor difference
    that's not noticeable to a single user might be amplified when trying to run
    multiple users on the same system. I would not disable SMART, though,
    unless you're sure it's responsible for a big performance hit. I would not
    have thought SMART could effect performance, but I don't know all that much
    about it.

    IMO Intel's been a little disappointing with their drivers for recent
    hardware and new operating systems. My home motherboard is still a current
    shipping model (but one of the older ones), and the Win7 drivers didn't work
    with every component - I had to dig around to find a solution in the forums.
    And, they never released Desktop Utilities for Win7, which is inexcusable.
    This is going to have me revisiting my love of Intel motherboards next time
    I upgrade.

    Re: High CPU usage and slow response

    Thanks everyone for your suggestions.

    I have already suggested to the client that RAM should be doubled. That
    should make some difference.

    I will also perform a Windows Update and update the Intel drivers.

    I still fail to understand how limited RAM etc will cause the CPU usage to
    skyrocket. With nothing unusal running, Task Manager itself sits firmly at
    25%. Limited RAM will cause swapping (excessive disk activity) but not,
    AFAIK, high CPU (though I may stand corrected).

    I'll report my success, or not, later on.

    Thanks again everyone for your advice.

    Andrew

    Re: High CPU usage and slow response

    I have inherited a similiar situation, almost to the letter, but SBS 2003
    instead of 08 on a desktop board with an onboard controller. Now that the
    previous IT "Pro" is no longer around the customer is moaning the performance
    as he sits at the console to fix things the previous "consultant" did not
    finish or worse, broke. I have to remind him that the server is not used
    like this normally and so what if emails arrive .01 seconds later becuase
    the drives spin slower?

    Admittedly it is agrovating that the WSUS approval screen takes 15 or 20
    seconds to refresh everytime you approve an update, and that the Server Manager
    takes what seems like a week to come up after logon, but this is a problem
    only the admin will face.

    The real test will occur when the system is actuall put into day to day use
    and the uses can't load their word docs "fast enough", or accounting can't
    get their AR reports to process timely. It will either be bearable or unbearable,
    only time will tell.

    In your case, add the RAM and see if it becomes bearable. <g>

    Re: High CPU usage and slow response

    All sorted.

    The client got the mobo changed to a server board, got 8Gb of RAM and
    installted an Adaptec RAID card.

    Much nicer machine to work on - doesn't behave anything like the old desktop
    box.

    Thanks everyone for your input, it made a difference.
