Bingo! Setting 'noAck' = true on basicConsume increases messages received to
about 33K per sec.

As to the low send rate --

Not so fast! (so to speak;-) -- rabbit .Net client uses TCPClient, 
which "provides simple methods for connecting, sending, and receiving 
stream data over a network in synchronous blocking mode."
