Windows Server 2008 is 20% faster than Vista

Strangely enough. I have not found enough benchmarks to backup this claim. I will wait if no one comes with something interesting. I will have to find out by myself.

I'm feeling the same, often when some1 claims something to perform a lot better etc. when testing myself in benchmarks and games etc the results were far from impressive.

This 20% is most likely a special scenario but I'm willing to bet run typical benchmarks and you'll witness probably a complete different story. Vista SP1 scores 500 points lower in 3DMark06 compared to XP SP3 for example, I doubt Win 2k8 would be much better either.
