I tried using multiprocessing.Pipe() and send_bytes()/recv_bytes() to
send messages between processes:
8 bytes messages -- 525,000 msgs/sec
15 bytes messages -- 556,000 msgs/sec
So the size of small messages does not seem to make much difference.
(This was in a Linux VM with Python 2.7. Python 3.3 is much slower
because it is not implemented in C, but gives similarly close results.)
