Remember, most OSs don't show you a good representation of time waiting
for I/O. So, if 30% CPU usage better or worse that the invisible or
poorly represented I/O usage? I don't know the answer, but at least
keep the question in mind :-)

Multicasting should be very very cheap? What OS are you running?

You should really post the message to the mls mailing list for that kind
of response :-)
