Running a task with a period of 10us is usually considered a bit out of
the scope of Xenomai. Nevertheles, there were some recent improvements
on Xenomai trunk that might make this possible. It would be interesting
if you tested this with trunk and tell us whether it works.

Also note that in order to get ultra-low latencies, you have to properly
calibrate the nucleus latency (/proc/xenomai/latency).

Adeos has no notion of a "task", so, you would have to implement your
task in an interrupt handler, and yes, you would get better performance
(see for example the difference between latency -t 2 and latency -t 1).

Well, you are not asking on the right mailing list. Try RTAI mailing list.
