FFMQ is a fully Java, lightweight, fast native JMS 1.1 implementation. Emphasis is made on raw performance and reliability. As a consequence, it does not provide a lot of features but it's fast, easy to configure, and has reduced dependencies.
This is the first stable release of the new 3.x branch. This major version provides improved performance, horizontal scalability, better JMX support, and a completely rewritten storage engine (asynchronous and journal-based).
