I think the performance difference you are seeing there are just the effects of Windows 7 not using every last system resource like Vista does. It's great to come out of a game and see 600MB memory usage, not 1.6GB like Vista. So I'm pretty sure the performance increases in Windows 7 comes from the superior resource management and the fact that the OS isn't sucking your CPU and Ram constantly like Vista does.
This OS runs on laptops that could not even run Vista. There is a big performance difference between this OS and Vista, it's not just a coincedence.
