    Setting 'System managed' page file for d: drive causes high CPU us

    Hello!
    Setting 'System managed' page file for my d: drive (EIDE Samsung SP2514N on
    JMicron JMB363 PATA and SATA controller on my Asus P5K motherboard) causes
    explorer.exe to use about 90% of CPU after a restart for several minutes and
    in about 10 minutes intervals during 720p video playback in VLC Player for
    several minutes.
    RAM 6GB, CPU Intel E6750. Vista Ultimate x64.
    I have set 'no page file' for my d: drive (EIDE Samsung SP2514N on my Asus
    P5K motherboard) and the problem disappeared. Why does setting page file for
    my d: drive cause the high CPU usage? My d: drive is least frequently used.
    I have not changed 'System managed' for my G: drive.
    I have set 'System managed' for my c: drive (WD5005000AACS ATA) too, and the
    problem have not reappeared.
    Regards,
    Dima

    You only need ONE page file for your entire system - you do NOT need one for
    each drive......and if these drives are partitions and not
    physically-separate hard disks then there's no advantage in moving the page
    file from C drive either....

    Thanks Gordon for your reply!
    I have 3 HDDs: 2 SATA: C: and G: and one EIDE d:. I do not have logical
    partitions. MS writes that Windows uses a page file on a less busy HDD at a
    time. The busyness changes over time, therefore MS recomends to spread a page
    file over all phisical HDDs.
    What program can assess performance with different locations of a page file?
    I want to compare different locations of a page file.

    Dima

    Never heard that one before - can you post a link to that?

    i suggest then that you create a very small page file on C for the memory
    dumps and create a partition on your least-utilised HDD purely dedicated to
    the second, windows-managed pagefile.
    (The article only mentioned TWO page files as above, not one on each
    drive....)
