Mine is running at 13% unless I am using Firefox in Windows. It's the best I've seen for idle cpu with XP running, and the memory footprint is pretty much unchanged.
Edit:
I should add that I have gone through my Windows services manager and shut down everything possible that still allows Windows to run. Wiindows does an astonishing number of things while you're not paying attention, and I really don't need the bulk of it, and possibly many of you also don't need it.
There are web sites out there that provide guidelines for deciding what to stop and what to allow, and it's well worth looking into. This should probably be added to the list started by someone for improving performance of Parallels. It's often more a case of making the VM more efficient rather than anything Parallels is doing.
