Subject [jira] Created: (OPENJPA-1517) Reduce locking in LifecycleEventManager
Date Wed, 17 Feb 2010 20:20:27 GMT
Reduce locking in LifecycleEventManager

                 Key: OPENJPA-1517
             Project: OpenJPA
          Issue Type: Improvement
          Components: performance
    Affects Versions: 2.0.0-beta
            Reporter: Rick Curtis
            Assignee: Rick Curtis

In recent performance runs I found that LifecycleEventManager.hasListeners(...) is a major
bottleneck when running with caching enabled. In a java core file that I was looking at there
were 15 threads all waiting to enter this method.
