In your performance experiment ZeroMQ will always be slower than TCP. There is a small overhead to using ZeroMQ but it's mitigated by other smart things it does like smart batching to avoid redundant network stack traversals. But if all you're doing is a synchronous PING/PONG, you lose that speed benefit entirely and might as well just use TCP.
ZeroMQ's value-add over TCP is stuff like API simplicity, asynchronicity, message queuing/routing, multi-cast, atomic multi-part messaging, etc. If speed is your concern, I would suggest redefining your problem and try to model it asynchronously. One embodiment might be: Use PUSH/PULL to distribute the work and PUB/SUB to aggregate the results.
