Looks like Windows 7 is some computing platform!

Sergio's 10hr P95 run on Win7 resulted in about 550 tests done on each core. Tom's 14hr P95 run on Vista, however, got about 630 tests done on each core. If we extrapolate Sergio's P95 speed, to get 630 tests done it would only need about 11.5 hours! That's a whopping 2.5 hrs ahead after a half-day racing just by upgrading the OS!

I am very impressed.. Did you tweak something on the Win7, Sergio?
