the results were mixed. Boot times, despite dedicated tweaking from Microsoft were slightly worse than in Vista SP2 or XP SP3 (by over a second). Shutdown times, though, showed much improvement over the slow XP, and even some improvement over Vista. Since the 7100 build, Windows 7's performance in Microsoft Office and iTunes has improved significantly. In the Office benchmark, though it still gets beat by both Vista and XP.
The numbers themselves are less than impressive, as you might imagine from their inability to best their nine year old OS. Modern GNU/Linux, of course, spanks them all."
