Nevertheless, Sven, it would helpful to know details about your computer---motherboard, bios version, cpu, ram, etc. Like Michael said, "I do not see yet how an OS version change should make much difference here." Yes, we want to help you get back your performance, but we also want to be able to characterize how an OS version change may or may not affect others. I personally don't believe that a change to another distribution will recover anything like a 30-percent drop in performance. One of the things I've been annoyed by in recent distributions is the ever increasing requirement for hardware support of OpenGL and its extensions. A recent rant http://www.phoronix.com/scan.php?page=news_item&px=MTIxMTg is instructive. With this in mind (and you did mentioned graphics first), have you tried my favorite trick and run your LinuxCNC host in headless mode, using another computer to provide X services? A quick test would confirm if you are being undone by your host's graphics subsystem.
