It was already done, thanks for the tip, I am more than a little bit ignorant here, but I think this things must be explained at the home page as a big advantage over other OSs.
Here is the link where i begin to learn about this - I use to read comments usually I learn more from them than from main articles -http://www.tomshardware.com/reviews/ubu ... l#comments

Talking about the results, I think Ubuntu won it's own share of tests versus Windows 7. Unfortunately, I think Ubuntu is one of the worst Linux distros out there to be tested, and it doesn't represent what REAL Linux is.
First of all, its kernel is really VERY unoptimized. Windows has a 300Hz tick ratio, whereas Ubuntu is configured with a more "server-alike" 100Hz tick ratio [try to use preemptible Ubuntu kernel with a 300Hz/1000Hz tick ratio (or CK's BFS) to see what's good for gaming and encoding/decoding tasks
Secondly, it's known that using compositing affects the performance of gaming with NVidia cards+Linux combo. You can find that evidence in Phoronix (a linux-friendly benchmarking site).
Finally, as Ubuntu is a 6-month release distro, and not a "rolling-release" one, some of their packages are already obsolete and might not reflect the performance of newer packages. So, as a suggestion for the next tests, I'd like to see some Linux vs Windows benchmarks with 2 different distros. One of them could be Ubuntu (as the worst-case scenario), the other one could be something more optimized like Arch Linux (I suggest ArchBang), Gentoo, or the more popular PCLinuxOS.
