I don't think think this is specific to rawhide, but it seems maybe a bit worse in rawhide, so I'm asking on this list. I have a gnome terminal running an app that prints a lot of lines (perhaps 60 100 character lines per second). This causes Xorg to use about 50% of my CPU as reported by top, and X responsiveness is really bad. I'm running the vesa driver due to this problem: https://bugzilla.redhat.com/show_bug.cgi?id=504048 So maybe not running a driver optimized for my hardware is part of the problem. But it seems worse than I would expect or than I have seen doing similar things on the same hardware in older fedora releases. And the interesting thing is that the Xorg CPU usage doesn't change much if I minimize the gnome terminal... I would naively expect that X would not consume much CPU printing lines to a minimized terminal. And in fact, if I do the same thing in an xterm, the Xorg CPU load does go way down when I minimize the xterm window. Why does a gnome terminal make Xorg suck more CPU printing to a minimized window than an xterm does? Thanks, David PS - Here's a little test app that demonstrates the problem on my system: #include <stdio.h> #include <time.h> int main(int argc, char *argv[]) { struct timespec ts; ts.tv_sec = 0; ts.tv_nsec = 1e9/60; while (1) { nanosleep(&ts, NULL); printf(" 1234 14327.8 xyzabc blah 3 0.00000000 0.00000000 0.00 0.00 0.00 0.00 0.00\n"); } } -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
