"Ending out May, we have an interesting set of tests comparing the performance of Fedora 15 and Ubuntu 11.04. This is looking at the "out of the box" performance of both operating systems on three different systems. Not only is the actual test result looked at, but we also compared the power consumption of the two operating systems."
