    Queue cache or persistance I/O slowdown

    Jay Wright Newbie

      I'm running performance tests with a JMS application on both 2.4.9 and 3.0.3 on solaris. Same code.

      In 3.0.3 I am having performance issues where the io wait is around 20% and we can see that about 300kb are being written to disk each second. But I can't figure out where. I don't see any files growing. I hope it's just an ill-configured cache or persistence manager.

      In 2.4.9 it runs without problem, no io wait, so it's not any logging or application induced i/o.

      For our application, we do NOT want to persist any messages.

      Has anyone seen this problem in porting to 3.x from 2.x?
