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