Netty-socketio Overview === [](https://maven-badges.herokuapp.com/maven-central/com.corundumstudio.socketio/netty-socketio/) This project is an open-source Java implementation of [Socket.IO](http://socket.io/) server. Based on [Netty](http://netty.io/) server framework. Checkout [Demo project](https://github.com/mrniko/netty-socketio-demo) Licensed under the Apache License 2.0. Features ================================ * Supports __0.7__...__0.9.16__ (netty-socketio 1.6.6) and __1.0+__ (netty-socketio latest version) version of [Socket.IO-client](https://github.com/LearnBoost/socket.io-client) * Supports xhr-polling transport * Supports websocket transport * Supports namespaces and rooms * Supports ack (acknowledgment of received data) * Supports SSL * Supports client store (Memory, [Redisson](http://redisson.org), [Hazelcast](http://www.hazelcast.com/)) * Supports distributed broadcast across netty-socketio nodes ([Redisson](http://redisson.org), [Hazelcast](http://www.hazelcast.com/)) * Supports OSGi * Supports Spring * Lock-free and thread-safe implementation * Declarative handler configuration via annotations Performance ================================ Customer feedback in __2012__: CentOS, 1 CPU, 4GB RAM runned on VM: CPU 10%, Memory 15% 6000 xhr-long polling sessions or 15000 websockets sessions 4000 messages per second Customer feedback in __2014__: "To stress test the solution we run 30 000 simultaneous websocket clients and managed to peak at total of about 140 000 messages per second with less than 1 second average delay."
