ARTEMIS-2236 Address Latency Impact caused by ARTEMIS-1451
URL: https://github.com/apache/activemq-artemis/pull/2514#issuecomment-456708382
1451 removed synchronization in the class, by adding the overhead of
creating a new thread until threadpool is full, this though means that instead
of re-using an idle thread for new work, new threads are being created which is
expensive, and the point of thread pooling.
We have seen a 15-20% latency increase hit due to this.
