Phoronix: KWin Can Cause A Performance Hit Too
Last week we published Arch Linux vs. Ubuntu benchmarks to finally lay to rest that for the overall system performance the speed of the rolling Arch Linux distribution is not too different from that of Ubuntu when running with similar package versions. One of the areas, however, where the performance was different with the "out of the box" experience was the OpenGL gaming where Ubuntu was using Compiz by default where as Arch had Metacity. This surprised many so we published another article entitled The Cost Of Running Compiz where we showed the performance penalties of a compositing window manager with different hardware and drivers. This led some to ask whether the performance of KWin also causes the OpenGL frame-rate to drop, so here are those KDE benchmarks.
