Virtual Machine Settings and Performance (my non scientific tests)

I recently performed some very subjective non scientific benchmark results for how my new pc runs MOSS in a VMWare virtual machine. The pc is a Dell Dimension 9200 Dual Core with 3 gigs of memory, and unless I mention it specifically the tests will have both cpu’s turned on (you can turn one off in the vmware settings), 1.5 gigs of memory for the vm, a 20 gig hd pre-allocated to the vm, and will have hardware virtualization enabled in the bios of the host machine. I used PassMark Performance Test v6.1 trial edition to do the testing. I mainly just wanted to learn a little more about how VM performance works, since I’m fairly new to the concept. Hopefully someone else can learn something useful from my homework.

Based on my readings of the test (and perhaps should have been obvious from the start) its best to run with both cpu’s on, hardware virtualization on, and with the vm installed on a seperate internal hard drive.
