If I'm reading rour post right, you're specifying 20 msec latency and getting about 22, which is OK, but I think you should be able to get lower latencies (i.e., I don't see that numbers like 21.9012 are too good to be true - those are typical Macintosh latencies but I think in linux you should be able to do much better.)
