Yeah, this is what one would think.  The problem is that with the simple UDP
transport, there is no feedback connection from the receiver to the sender
for flow control.  The sender just sends data as fast as it can and much of
it appears to get dropped (presumably fills up what the kernel is willing to
buffer for the receiver then drops everything else).  Clocking the data out
at the playback rate from the sender at least assures that this will not
happen.  This is what the RTP plugin appears to do as well.  I've got some
fixes there also, but haven't got them assembled yet.
