I'm not familiar with the zmq_poller API so someone else might help - in general, a common optimisation is to drain the socket using non- blocking receives when poll wakes up (taking care of using heuristic to avoid starving the other sockets), so that you can process multiple messages per poll -- Kind regards, Luca Boccassi
