Well, I have been reading all these benchmarks, and most of them seem flawed. I know at times, Vista can be slower, but personally I think, that it isn't all the time. There are things I like about Vista and things I don't. I did a personal benchmark with the same hardware, clean install, and used PC Mark 05 and 3D Mark 01. I ran all the test 3 times. All from a cold start, so there was no caching from a restart or what ever there might be. Just thought I would share my results and hopefully I don't get judged, that this is a flawed test. Everything thing is ran with the latest drivers and all set to default, no optimizing was done. So here is the test...
Test Setup (Tried to keep the hardware similar to what a typical person would use) Pentium 4 (not dual core) 2.4Ghz Intel p865 chipset 2GB DDR 400 80 Gig Maxtor HDD Nvidia 7800 GS XP/Vista Driver 169.25 XP SP2 w/ current drivers and updates, and the same w/ Vista SP1 RC refresh
Startup time: XP - 37 sec Vista - 47 sec
3D Mark 2001: XP - 9805 Vista - 11122
PC Mark 2005: XP-3198 Vista - 2665
HDD XP startup: XP - 7.2MB/s Vista - 7.18 Physics: XP - 98fps Vista - 75.53 Transparent Windows: XP - 1040 windows/sec Vista 474 3D: XP - 189fps Vista - 180 Web Page Loading: XP - 1.82/s Vista - .94 File Decryption: XP - 48.27Mb/s Vista - 48.1 Graphics Memory: XP - 1352.59fps Vista - 1165.21 HDD - General usage: XP - 5Mb/s Vista - 4.97 Multi app test: 1 Audio: XP - 785.2kb/s Vista - 739.8 1 Video: XP - 106.14kb/s Vista - 97.75 2 Text: XP - 46.5 Vista - 37 2 Image: XP - 9Mb/s Vista - 8 3 File Compression: XP - 1.62/?

These tests took a looong time to do. So hopefully someone finds them useful.
