HI:
I tested the scheduling jitter of xenomai on a Pentuim platform. The largest jitter near 260 micro second. The largest jitter of RTAI on the same hardware platform is only about 15 micro second.
Were some options configured wrong?
regards Arethe

Probably. The most probable culprit are debug options.
