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

             Summary: Improved behaviour of the common thread pool under contention
                 Key: ARTEMIS-2177
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2177
             Project: ActiveMQ Artemis
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 2.6.3
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


Currently ActiveMQThreadPoolExecutor employ internally a shared LinkedBlocking queue that would always perform a lock to push messages into the queue and will signal to wake up any (if any) awaiting consumer thread.
This same behaviour could be improved both by:
- using a lock-free queue that would eventually signal any (if any) threads only if there is some
- using a work stealing pool
