    CPU Usage...100%

    Mmmm....SEEMS to be

    SearchFilterHost.exe s
    earchprotocolhost.exe and
    searchindexer.exe

    taking a lot of the CPU useage...it's STILL running at 100% when ALL I have
    running are WinMail, Task Manager and Sidebar (with 3 whole gadgets!!!)

    ....So...CAN I STOP those processes in Task Manager?

    Yes, but you will have the indexing finish after a period of time, depending
    on what you have set up to index. Why not just make them low priority tasks
    where they won't interfere with anything else you are doing and let them
    finish their tasks.

    Is the system responsive?

    Trying to get low CPU usage is madness - you don't get a discount on
    your computer for not using clock cycles, and you'll never get them back!

    If the system isn't responsive, I'd set their priority to low.

    Some with poor cooling setups could cause overheating of the CPU at 100% for
    a long period of time but that is the only reason for any caution. :-)

    To follow your "logic" you are implying if CPU useage shows 100% or
    close to it then whatever applications you're using are maximizing
    your computer's resources. Nothing could be further from the truth.
    This is a common misconception. The proper way to look at CPU useage
    is to judge how efficently your computer is running.

    An anology would be trying to pull a large trailer up a steep hill
    with your 1960's VW bettle. You would likey need to floor the gas
    pedal and if lucky you may be able to get up the grade with the engine
    huffing, puffing and straining under the load. If your VW had a
    resource meter it would be showing close to 100% useage but you as the
    driver sure wouldn't feel you car was working really well, in fact
    you're be worried if you're make it up the hill at all.

    Same with computers. If it takes nearly all your resources to do the
    tasks you are trying to do, then your computer is straining and likely
    it's response will be sluggish with telltale signs, like applications
    very slow to load, images taking for ever to show up or get redrawn on
    screen, long delays between pressing a key on your keyboard and seeing
    that character appear on screen, etc..

    This should not be confused with smarter applications taking more
    resources if they are not being used, but giving them back gracefully
    if other applications are started up.

    For example I use Sony's Vegas (a video editor) a lot. If running by
    itself it will "hog" about 95% of CPU cycles, however it doesn't need
    anywhere near that much, and if I start up my newsreader, word
    processor, open a spread sheet and play a some Mp3 file all while
    Vegas is still rendering a video, it will continue, but at a somewhat
    slower rate with the resource meter hardly changing, yet the demands
    on the system are not considerablly greater.

    What can compound the value of such "meters" is what is verses what
    can be accomplished in a given CPU cycle. Some things need to be
    handed off, other tasks do not, for example to a CPU's math co
    processor routines. Also some applications as well as interaction by
    Windows itself will impact how agressive a paging file is being used,
    page faults generated, etc.. So a computer showing only 60% CPU usage
    often is running more efficiantly then one running close to 100%. It
    all depends WHAT it is doing.

    That's putting an awful lot of words in my mouth!

    I'm saying that CPU cycles have no value if they're not used.

    :-) And right you are. A well written program should be able to fully and
    efficiently use whatever machine cycles are available to get its tasks done
    in the shortest time. It is up to the OS to allocate the available machine
    cycles based on the cumulative demand of the currently running processes
    requests.

    Re: CPU Usage...100%

    ....so, to my original query...when I installed Vista and ran Vista for 4
    weeks, my CPU, running EXACTLY programs to what I am running now, was always
    at around 40-60% (it DID vary)....but its been hard on a constant 100% for
    3 days (non continuous use)....

    .....ah......and AS I type this the meter has dropped to 5-7%
    .................and is staying there

    I find it odd

    Re: CPU Usage...100%

    Rod, I think this is probably normal and nothing to worry about. As has
    been said here already, high CPU utilisation is only a problem if it's
    making the machine unresponsive in other tasks.

    And if that is the case, then reduce the priority of the CPU hungry threads.

    Vista indexes the files on your hard drives (so that searching is
    quick), and this uses CPU time. When it finishes (making the first index
    takes a long time, as it has to index Windows and any third party apps
    you installed when you set up your computer) the CPU usage drops.
    I believe it runs low priority, so that it only runs when nothing else
    is using the CPU.
