-----------------------------------

             Summary: RWLock in queue does not used properly - performance =
improvement
                 Key: AMQ-4231
                 URL: https://issues.apache.org/jira/browse/AMQ-4231
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.7.0, 5.4.2
         Environment: fedora15; ubuntu 12.10; debian; probably independent
            Reporter: Tom=C3=A1=C5=A1 Martinec
            Priority: Minor


The full story is in the user forum under title:
Activemq 5.4.2 hangs when the temp disk usage is used

The advantage of RW locks in Queue class is not used much. The cursors obje=
cts are synchronized, so the readers cannot access the queued messages conc=
urrently.

The fixing effort of this issue may not be worth it, but you may consider t=
his issue during fixing related issues.
