Along this thought, I didn't notice what client alex chen is using,
but the amqplib doesn't disable Nagle.  I don't know if nagle has to
be disabled client and server side, but I would think it would.
Anyhow, for amqplib adding a TCP_NODELAY after the socket creation is
an easy thing to try, if alex is using amqplib.
