                 Key: ARTEMIS-1318
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1318

          Issue Type: Improvement
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


Disable the TimedBuffer on MAPPED journal if no data-sync in required:
* reduced footprint (no TimedBuffer)
* reduced CPU usage (less buffer copy and no TimedBuffer background timer thread)
* reduced latencies (not timeout can influence when the write will happen)
