Why is win7 so damn slow?

Fuck. I don't get it!!

I just made again a performance comparision between xp and win7, with video playback. Win7 needs at least 50% more power for the exact same task!

What i did, playback of the exact same file, with same codec and same setting on the same player:

CPU: Laptop P3 @1.2G
Player: mpc-hc
Codec: mpc's own
Codec: Xvid, SD 720x576, 16:9 anamorph
File: Railway docu, 2mbps

Both systems are clean, no av running, latest drivers installed. "mpc-hc.exe" shows on:
XP: ~45%
Win7: ~80%

Why?? They said that kernel manangment (comtext-switching) had been improved... yeah to need more power or what.

Anyone an idea? And please no comments like "buy new hardware", i've hardware modified and tuned this machine, running like a charm and love it (as long as i'm using XP).

I'm praying that there's someone with real professional knowledge about in-deep kernel modifing!

I'm sure that it's something about context-switching...

Last Edit: (so that you don't need to scroll to the last post)
I now have done multiple cpu-laod comparisions between xp and win7. I want one and for all to get rid of my dual-boot configurations and settle with one M$-OS at last.
Any Task needs about 50 to 100% more power on 7, no matter what machine. Here are for example the results from my good laptop: (CPU is running at lowest clock)

Playback of video trough EVR/VMR9
Win7: 53%
XP: 33%
Playback through VMR7:
Win7: 33%
XP: 20%

CPU load of Process Explorer and Samurize (which i use to isplay basic speed data alays oon top). Both in idle mode, cpu running on lowest clock:

Win7: ~ 1,5%
XP: < 1% (doesnt show any load most of the time)

That means any thread needs higher load on win7, causes a higher power consumption, has a higher drain on the battery and raises your energy bill.

So who is the more energy efficient OS?

Considered the still present features like Icoloumnprovider and a real hibernation progress display, has a lower memory foootprint and is easier to configure...

Windows 7 flies out of my room immediately!!! To be run over by a car

And i will use the freed hardisk space for linux and ReactOS. I've heard they are planning to switch into beta phase...
