Slowness when using VPC 2007 in Windows XP x64

I am using Virtual PC 2007 in Windows XP x64 SP2 on an adequately fast host
system (2gHz Core 2 Duo w/Intel Virtualization Technology). When I install
Windows XP x86 in a virtual machine, I get very slow, laggy performance (even
for a VM.) It is worse than another PC I use which has 32-bit XP as the host
operating system. Does anyone else experience this?

I have installed the VM additions. The VM has 512mb RAM allocated to it, and
my system has 3gb RAM.

Like Mark says, install the virtual machine additions from the Action Menu
on the vm console.

There are a lot of things that can slow a VM down. If you're using
any kind of power management that is throttling down your CPU, that's
the first place to start.

How much RAM...?

How much RAM have you allocated to the VM?

Have you installed the Additions...?

The host computer is a laptop. SpeedStep is enabled, but I do not believe
this is the problem because I have used another laptop of similar
specification (except running Windows XP x86), and it worked fine. Besides,
the only way to disable SpeedStep would leave my computer locked in lowest
performance mode.
