[zeromq-dev] ZMQException: Errno 48 : Address already in use

[Trevor Bernard]

JeroMQ actually has higher throughput than JZMQ. There is a heavy cost
when crossing the boundary between java and native JNI code. I would
suggest people start with JeroMQ unless they need a feature that it
doesn't support like inproc, pgm and currently security. It's far
simpler to get up and running.
