"by selecting a suitable process scheduler and configuring your HZ to 1000"
It is already done. (the Hz). Well thanks very much for these information (you and other people on this thread). I believe what you say but I believe too what I see with my own eyes. If we will ever meet on a Gentoo conference or anything, I'll show my faster X11 with negative nice level. ;) Anyway I'm running it with default nice level (0) for some days because X11 is very unstable with -15 niceness. 2008/5/15 Alan McKinnon <[EMAIL PROTECTED]>: > On Thursday 15 May 2008, Abraham Gyorgy wrote: > > I know X runs always as root.
