Dimension 8400 with Vista x64 MUCH slower than XP x86

    I upgraded my Dimension 8400 to Vista x64 hoping it would take advantage of
    the 64 bit CPU I have... tough experience so far. I have as many 64 bit
    drivers as I found on the Dell site and the manufacturers. The system is
    stable and that's already something. But performance is very bad. Burning
    DVDs takes 3x more time than XP x86. Saving DVDs takes also 3x more time.
    Disk IO seems to be pretty sloppy, despite getting a 5.2 on the Windows Vista
    Performance Index. I've got a SATA 160GB drive, which shouldn't be too bad on
    a brand new and clean image. Also put 2GB of fresh DDR2 RAM, it helps a bit
    but the bottleneck seems to be IO. Adobe Photoshop takes forever to load and
    operate. Frequently showing "not responding" for several seconds to perform
    basic tasks. Have you all seen something similar? Any guidance on what to do
    to improve IO? I went to Seagate's site and they said no 64 bit driver is
    needed from them. Thanks Nick

  2. Vista 64 does take advantage of your 64-bit CPU, 32-bit software however
    does not. I for one like Vista 64, but most here are going to tell you to
    install the x86 version of Vista.

    Well you have looked for drivers so if that has not worked either
    something didn't install properly or else it's not a driver problem.

    One thing you might check is look at drive properties and see if the
    "Index" box is checked, that made a big difference on my 64 bit desktop
    .... but installing the 32 bit version will be faster (It is faster on 3
    machines here) and XP will be faster still. I don't have any comparative
    figures but IO does seem slow.
