JS-Collider is an asynchronous event-driven Java network (NIO) application framework designed to provide maximum performance and scalability for applications having not too many connections but significant amount of network traffic (both incoming and outgoing).

Performance is achieved by specially designed threading model and lock-free algorithms (learn more)

Main features:

simple and flexible API (learn more)
UDP (with multicast) support
shared memory IPC support out-of-the-box (learn more)
no GC overhead on income data, only one allocation per output message
plain Java 1.7 (no any unsafe cheating)

Refer the Wiki for API documentation and performance tests results.
