    SPTD slowing down VirtualBox

    Hi,

    Several months ago I wrote a topic:
    Code:
    https://forums.virtualbox.org/viewtopic.php?f=6&t=41879
    VirtualBox is installed on host machine with Windows XP SP3 and ... Daemon Tools with active sptd service.
    Different virtual machines (installed Windows, Linux, Live CDs ...), different settings and different versions of VBox but problem always is the same - very poor performance of machines inside - sometimes useless.
    Most of the time CPU load in VMs is 100% and 50% on host (dual core CPU).

    Discovered that disabling sptd.sys resolve the problem.
    (BTW: updated sptd to 1.79 - same problem.)


    So I wondering where the problem is exactly - in SPTD or VBox ... ?
Working...
