The SPECjms2007 benchmark was announced today. The benchmark has two performance metrics covering horizontal and vertical scalability with the tests consisting of a mix of publish/subscribe and point-to-point, durable and non-durable, persistent and non-persistent, and transactional and non-transactional messages. Given the contributing organisations (Technische Universität Darmstadt, IBM, Sun, Oracle, BEA, Sybase and Apache) it will be interesting to watch as results are published.
