Actually VMWare gets very close to raw performance for operations that do 
not need to be trapped by the VM. In other words, I have observed VMWare to 
be quite fast for certain applications. For example, VMWare is fast enough 
to saturate 100 Mbit connections.

VirtualPC on the other hand is an emulator (think bochs) unlike both the old 
Plex86 and VMWare so you can't make a fair comparision.
