Using libzmq 4 2.5 on centos 7. Getting very high latency when messages are sent from dealer to router and even from router to dealer. So i wrote simple client-server program using tcp and sent messages between them just for comparison. Tcp appears to be fast.
Sending single byte from dealer to router, zmq takes 900 microseconds.
Sending single byte from client to server, tcp takes 150 microseconds.
What am I doing wrong. I thought zmq will be atleast as fast as tcp. Is there any tuning I can do to make zmq faster?
