I tried using multiprocessing.Pipe() and sendbytes()/recvbytes() 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.

To the contrary, the lesson is clear: to speed up multiprocessing, the larger the messages the faster it goes ;-)
