Full x86 VM solutions:
VMWare, old Plex86, VirtualPC - qualitatively agreed are all extremely slow
:-)  This is because they are spending a lot of time performing
modifications of code segments to work around the x86 virtualisation

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.
