Windows 7 x64 - DOS VM is really really slow

Was running Virtual PC on an XP box and have now moved to a Windows 7 x64 box. Moved over the 18mb (yes, mb!) VHD file that is running a DOS application. Set up a new VM, pointed to the VHD file and it runs fine. Problem is that is runs nearly 5% as fast as the old XP box running Virtual PC. Where keypresses were instantly recognized they are lagging now. All the settings are the same. Obviously no integration services installed.

Virtualization is turned on in the BIOS of the PC.

try and download the dosidle application.

This utility is very useful when dealing with DOS inside emulators and virtual machines. Most versions of DOS (among other operating systems) don't handle the 80x86 HLT (halt) instruction properly, causing a constant full usage of the CPU. For more information about this, see the DOSIDLE documentation, sections 1.1 and 2.1.

No dice. vpc.exe is still sucking up 100% CPU.

DOSBOX was the way to go. Get the Hal9000 MegaBuild if you want printing support.
