Depends on the VMWare version and configuration... I can say that a VERY
BIG brazilian magazine store (known countrywide) uses VMWare to the
bones. Dozens of virtualized servers and even call center desktops are
on VMW software.
Works OK. But the free VMware server 2.x is really heavy a lot (1.x was
much lighter).
