Today CNet blog posted an entry related to Windows virtual machine performance on the Mac and it is interesting article to read when VMWare(VMW) when to IPO. VMWare Fusion 1.0 seemed to out perform Parallels in all the scenarios except that the Fusion is not able to run Quake 4 where as Parallels was able to. Not sure if it is a legitimate test as Fusion was using more than one core in the tests along with 128MB RAM where as Parallels was restricted to single core(it does not yet support multi-crore) along with 64MB.
Using Bootcamp is the best choice as it runs the Windows natively and lately I only boot to Windows using Bootcamp
instead of using any of the virtualization software as I always end up into some sort of problems (like OS and/or office activation and random crashes and white screen of death).
