The sad thing about this benchmark is that the next time Phoronix does a * vs. Linux benchmark (* being OSX, Windows, BSD, etc) Ubuntu will still be used as the reference Linux distribution, even though Fedora out performed it across the board. (Not only graphical performance due to X.org version - but also C-ray performance [page 4]).
Now undoubtedly there are better performing distributions out there that can give both Fedora and Ubuntu a run for their money (In my experience [and I'm an avid Fedora users], using XFCE instead of GShell 3.2 has a major effect on performance - at least on low end machines) - isn't it high time the reference Linux distribution will be elected based on, errr, performance instead of install base size?
