You need to use both equally mechanisms for whatever they are most effective: "kqueue" for scalable sockets and "poll" In order for you it to operate :) As for prioritising I/O: underneath unusual instances you have got the case in which some fds need to be viewed and handled in a short time (with reduced è²å¾‹è³“éŠå¸ä»£è¾¦ latency), and in many cases
