If I may differ, it *sometimes* makes the performance of systems using SCHED_FIFO-scheduled threads better. When I tried it, my system fell to pieces, and I was unable to figure out how to tune it back to working in a reasonable amount of time (say 40 hours). So I've been sticking with SCHED_FIFO without Ingo's RT patches. At least this way things basically work with enough buffering. Although somehow regular priority threads (and processes) still manage to interfere with my SCHED_FIFO threads. Maybe I should bring this up on the dev list again. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
