I've been serving Django and PHP apps with uWSGI for a while. After some reading this morning I decided to give Circus a shot to manage the whole Python web stack behind Nginx since I've departed from PHP entirely.
My work machine is running Ubuntu 15.10. The libzmq version installed is 2.2.0. Circus wants >= 3.2. It fails gracefully and builds a libzmq Python extension.
Is there a performance drawback to running Circus with the Python zmq extension instead of the native system library? I wouldn't think there would be a problem, but the large warning message with a built in delay leads me to believe the developers think it's less than ideal. I don't know enough about how Python extensions work in this context to know if there's any performance overhead involved.
