Wow, great idea! It’s pretty amazing that there was such a small difference between the two.

This might depend on the hardware.
Is this running on a machine with a hypervisor?

If the system doesn’t have Intel’s Vanderpool or AMD’s Pacifica how does Vmware perform?

But SuperPI is used in many system performance benchmarks. I think it’s rather relevant for a virtual machine benchmark.

If I were to test 3D, obviously there are none and graphics support on all three platforms vary way too much.

If I were to test hard-drive, then I’d have to make sure each machine had a defragmented and equally sized hard drive. Not worth testing IMO.

The only thing left reasonable to test was arithmetic calculations, thus, SuperPI.

SuperPI seems to be CPU bound – it calculates the approximation of the pi, after all. The drive/defragmentation shouldn’t have any impact on its performance, assuming that no other activities are taking place in the background of the VM. The program reports 33 megs of allocated memory, so there should be no swapping.

In other words, it’s not a representative piece of software for testing the virtualization.
