    'Processes' Bogging Down Audio App? (Home Edition)

    People,

    I recently upgraded my digital audio sequencer from SONAR XL 2.2 to SONAR 4.

    The new version is a heavily graphic laden, sluggish performance CPU hog.

    (sorry to be so crass...but that's about the size of it.)

    After trying all kinds of fixes & system tweaks (& most of my XP audio tweaks have been in effect for 2 years), one of my engineering friends thought the upgrade may be more affected by "Processes" running in the background.

    I brought up Task Manager > Processes, while SONAR4 was running; & found the following list:

    taskmgr.exe
    RDSMIDNT.EXE
    SONARPDR.EXE
    wowexec.exe
    ntvdm.exe
    symlcsvc.exe
    svchost.exe
    NOPBD.EXE
    SAVscan.exe
    nvscv32.exe
    Crypserv.exe
    CCproxy.exe
    spoolsv.exe
    CCEVTMGR.EXE
    SNDSrve.exe
    CCSETMGR.EXE
    explorer.exe
    realsched.exe
    svchost LOCAL
    svchost NETWORK
    svchost SYSTEM
    svchost SYSTEM
    CCAAP.EXE
    lsass.exe
    services.exe
    winlogon.exe
    csrss.exe
    smss.exe
    System
    SystemIdleProcess

    The largest Memory Usage culprits were:

    SONARPDR.EXE: 263,956 KB
    explorer.exe: 22,460 KB
    svchost SYSTEM: 17,976 KB
    CCAAP.EXE: 13,884 KB

    ...but none took up any more than 2% CPU, except for: "SystemIdleProcess", which was taking up 98 !!!

    My XP bible (Windows XP Inside Out, by Ed Bott & Carl Seichert), describes "Processes" as all active subsystems & services managed by the OS...so if something related to the system was causing slow performance in an app, this is where it would be found, correct?

    So:

    A) Does this list (& it's values) look normal?

    [img]/forums/images/smilies/cool.gif[/img] Would these running processes cause an audio multitracking program to bog down?

    Thanks,

    First, SystemIdle represents the amount of your processor NOT being used during the last measurement period. So, 98% idle means nothing much was happening. Next, have you check the SONAR support site? http://www.cakewalk.com/Products/SONAR/default.asp. There are also user forums where you may get better help from someone familiar with the product.

    There's no such thing as a 'normal' processes list, but yes, there seems to be nothing out of the ordinary in your list. In addition, I wouldn't expect a system such as yours (plenty of RAM, plenty of CPU 'ooomph') to be having problems with that lot, a fact borne out by the 98% system idle process. It seems to me that your problems aren't being caused by process overload, but rather something else, possibly an audio driver issue. Are you running the latest version of Direct X (v9.0c) and do you have the latest drivers for your soundcard?

    My suggestion is to eliminate everything at startup and see if the problem goes away. If it does, you begin re-enabling things one at a time until the problem comes back. When it does, you have your offender.

    Try using a program like Autoruns or similar to control what is starting and what sits on its thumbs.

    Thanks people...

    Good info...very helpful.

    2 more questions:

    1) JFTHOI, I tried to end a few Processes (from within Task Manager); & nothing happened. A warning window popped up, telling me bad things may happen if I do, but none of the usage numbers changed (for any Column.) How does one tell if in fact a process has been ended?

    2) With an app like autoruns, will any changes be permanent? I want to make sure I could turn off certain Processes or Services; & have then come back next time I reboot.

    Thanks again,
