My company has been using with Socket.IO for async communication in production for a little while, and while it worked great in private beta, it has serious performance issues (as well as memory leaks) with only ~ 500 concurrent users. Ouch. The trouble with Socket.IO is that it tries to do too much. It doesn't live at the right level of abstraction.
The ideal solution would be a networking layer with proper fallbacks (websocket -> flashsocket -> xhr -> jsonp, et al) that handles client handshaking and *nothing else.* After dealing with a lot of issues around a load-balanced socket.io server [1], I believe the better library to utilize would be SockJS [2]. SockJS has a spec, a solid client library and some server implementations (netty version in beta, vertx supposedly works out of the box). I haven't used SockJS yet (it will require a few small server/client libraries to do proper multiplexing), but it's likely the direction we're going to be taking since the situation with SocketIO appears to be pretty dire as of late. Our software usage really kicks up 2-3x during the fall (higher-ed focused company), so we'll be forced to move sooner rather than later. What would be really-really awesome would be a core.async + http-kit powered library. Just throwing that out there :P [1] https://github.com/learnboost/socket.io/issues/438 [2] http://sockjs.org Shameless plug: if you enjoy problems like these and would consider moving to Dallas to solve them, reach out to me: clifton [at] orgsync [dot] com -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
