Well, of course not. It's completely absurd that Windows runs better in a VM. When I tried it, I expected my work "computer" at home to be impossible to use, so I would go and fetch some hardware at work. I was very surprised that it actually performed better than the work hardware (on anything that isn't CPU bound). (And yeah, as much as Windows lags behind on those benchmarks, it's not nearly enough to explain what I've seen.)
There is some other comment hinting at the VM ignoring some fsync barrier. I've seen the VM caching a lot of disk IO, but there is probably some very stupid application level choice involved there too. But on Windows, it doesn't have to be fsync, as there is locking too to ruin your day.
