The difference between 8 and 15 is, e.g., nearly doubling the amount of network traffic (for apps that use pickles across processes or machines).
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.) -- Richard
