It's common knowledge virtualization is very useful, but raw performance takes a hit. Today I decided to install Ubuntu on a small section of my Vista disk and try this whole virtualization thing. Well, check out this screenshot:
This is the *same* benchmark done using Prime95. I don't know what the really small numbers in the Ubuntu window mean (the ones <1ms), I figure they're some kind of anomaly. Nevertheless, those numbers are supposed to be bigger; however, the numbers produced by my (native) Vista install are slower. Virtualization is supposed to be slow, isn't it?
Edit: For a CPU-only test, it makes sense that performance doesn't take a hit. What's really confusing to me is that the virtual benchmark is faster.
