Those are great results! I don't know how xen handles scheduling but I'm always careful with anything that might add latency to the scheduling or timing. 1ms resolution is the minimum needed (a little less can be accepted since jitterbuffers can usually handle that). Did you use the -p option to opbx (it makes it run with higher priority)? /B - -- * GPG-Key: http://evil.gnarf.org/mrbk.pgp A: Because we read from top to bottom, left to right.
