is this on a previously quiescent connection (TCP or UDP) ? my
impression is that once things get rolling round trip times are pretty
good, but that moving a packet or two when there's been no traffic in
a few msecs produces much worse numbers. my impression may be wrong.
i'd also like to point out that the lowest value mentioned above is
more than 10% of the total time available to process a 64 frame chunk
of audio at 48kHz :)
