Windows 7 beta 1 performance - How does the OS compare to Vista and XP?

I’ve decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests to find out which OS comes out top.

There are 23 tests in all, most of which are self explanatory:

1. Install OS - Time it takes to install the OS
2. Boot up - Average boot time to usable desktop
3. Shut down - Average shut down time
4. Move 100MB files - Move 100MB of JPEG files from one hard drive to another

6. Network transfer 100MB files - Move 100MB of JPEG files from test machine to NAS device
7. Network transfer 2.5GB files - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from test machine to NAS device
8. Move 100MB files under load - Move 100MB of JPEG files from one hard drive to another while ripping DVD to .ISO file
9. Move 2.5GB files under load - Move 2.5GB of mixed size files (ranging from 1MB to 100MB) from one hard drive to another while ripping DVD to .ISO file
10. Network transfer 100MB files under load - Move 100MB of JPEG files from test machine to NAS device while ripping DVD to .ISO file

These series of tests will pitch Windows 7 build 7000 32-bit against Windows Vista SP1 32-bit and Windows XP SP3 32-bit. The scoring for each of the tests is simple. The winning OS scores 1, the runner up 2 and the loser scores a 3. The scores are added up and the OS with the lowest score at the end wins. WINDOWS7 WINS..
