  • Supports SSL
  • Supports client store (Memory, Redisson, Hazelcast)
  • Supports distributed broadcast across netty-socketio nodes (Redisson, Hazelcast)
  • Supports OSGi
  • Supports Spring
  • Lock-free and thread-safe implementation

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." (c) Viktor Endersz - Kambi Sports Solutions
