Waiting For Windows XP
It's an article showing real-world (IT) testing of Windows 2000 vs. Windows XP. Yes it's possible to tune Windows XP down to get it more lean and working better, but it will never be as fast as Windows 2000 is on the same machine.
Under Win2K, I can average about 140 fps using Quake 3 at 1024x768 High Quality settings. Under XP using the same settings (and the same drivers), it's around 120. Doesn't seem like much for some people but hey, framerate is life in a first person shooter. I've done this test myself on many machines over the years, and 2K is just faster, period. XP can't touch it.
Funny thing though: Windows Server 2003 is
almost as fast as 2K is right out of the box. In terms of raw speed, 2K3 is pretty sweet. Of course it's a server OS but that just means it's tuned from the install to do a lot of things better.
Just my $.02.
