I put some fixes in FreeBSD-Current to avoid round robin context switches between equal priority RTP_PRIO_REALTIME processes, and it offers the POSIX interface as well as the RTP_PRIO interface, and I've tested it to see it works as advertised. You could try it and see if it behaves the same. Peter -- Peter Dufault (dufault@hda.com) Realtime development, Machine control, HD Associates, Inc.
