[jira] [Created] (ARTEMIS-3303) Default thread pool size is too generous

Francesco Nigro created ARTEMIS-3303:
----------------------------------------

             Summary: Default thread pool size is too generous
                 Key: ARTEMIS-3303
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3303
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


By tweaking thread pool size from default it's possible to easily gain twice the troughput: both Netty (acceptor) and global thread pool default sizing seems too generous according the available cores of a machine: 
* 3 x cores for the former
* [0, 30] for the latter (!!!)
