Re: [Python-Dev] Accepting PEP 3154 for 3.4?

[Richard Oudkerk]

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.

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