paho receiver not support nio ? #473

Open jizhenfang opened 6 years ago

jizhenfang commented 6 years ago

hi，I have meet a performance issue in paho. It's only 3000 tps from paho client to rabbitmq (MQTT broker), but the cpu , memory ,io usage is very low. I have saw the paho's resource code and The CommsReceiver use socket.getInputStream() . I think maybe here is the problem. Is it right?

Hi,

3000 tps is pretty impressive for the Java client! Moving to nio could be a good improvement further down the line, but it might require significant refactoring in a very sensitive part of the client so it's currently not at the top of our priority list. You're of course welcome to try moving to it yourself if you like?
