I have a 2000 server running Exchange and Terminal Services on a P3-based computer with SCSI drives and 2 gig of RAM. There are no performance issues at all with the system currently. I would like to virtualize it so that is running as a virtual session under 2008 64 bit version with HyperV and the latest greatest hardware platform and 8 gig of RAM. On paper the specs of the new hardware system - quadcore 2.83 MhZ and Raptor drives - are approximately 3 or 4 times as powerful as the old system so there would be a dramatic performance improvement if I ran the old system native on the new hardware. What kind of performance hit would I take virtualizing it? As long as it's as fast after virtualization as the old system that's fine. Again, there is no need at all for performance improvement.
