    Enabled dual processors in my XP VM and now browsing is noticeable slower.

    Used the following hack and indeed it did work:

    rundll32 syssetup,SetupInfObjectInstallAction ACPIAPIC_MP_HAL 128 %windir%\inf\hal.inf (requires two boots).

    Now, when I run task manager, I indeed see both processors. Now, though, my browsing is noticeable slower to launch and even browsing to another website is noticeably slower. Going to soon recover back to a golden set point, but curious if any others know of a solution or reason why this is so.

    I suspect the VM cannot implement by proxy what the hack tells XP to do implicitly...unless you've seen examples of it working on a VM.

    May so F.U.N.; again, it works, but it actually slows the OS down for whatever reason (not the opposite which you would expect). Oh well. Already recovered my VM and all's well.

    Yes, because XP is waiting half the time for a non-responsive processor maybe.

    or maybe his dual CPU setup doesn't really handle XP VM very well.
    I question what kind of CPU chip he has because he did not specify what CPU (Intel or AMD) he has on his computer and if the CPU "Virtualization" option is turned on in BIOS setup.

    Read the following when it comes to CPUs and Virtualization:
