A default timeslice of 20ms means a pathological client can ruin up to two frames per scheduler tick. And a fifth of a second is just insane. Pick two different numbers out of the hat. A 5ms slice means you can probably keep up with two or three abusive clients, and letting it burst to 15ms should give you about all the timeslice you need for a fullscreen game (that's doing server-side rendering for some reason). If you're running on a system with a 10ms granularity on SIGALRM, then this effectively changes the intervals to 10ms and 30ms. Which is still better, just not as better. I suspect this is about as good as we can do without actually going preemptive, which is an entire other nightmare.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
