We have seen a similar performance degradation running for customers running on JRockit, and encountered liveness failures as well, due to the thrashing / stampeding try to acquire locks. So we advise our customers not to use JRockit! (Doctor, it hurts when I do this, etc). I can't recall if we raised a support ticket with Oracle - I think we did and were advised to upgrade the version of JRockit, which had a very minor improvement but didn't fix the issue. Cheers, James
