Well, 8000 interrupts/second costs you something.

(The tasks are using 0%.) I didn't have this issue (as far as I know) with RTAI, and I didn't have this issue when using aperiodic timing mode. What I need is to have all my tasks locked to some timebase, and was told in a previous discussion that this was the way to go. Is there any reason it should use so much CPU time?
