franz1981 edited a comment on issue #2524: ARTEMIS-2240 ActiveMQThreadPoolExecutor should use LinkedTransferQueue URL: https://github.com/apache/activemq-artemis/pull/2524#issuecomment-457884054 On my box I'm getting the same performance of the master version for single producer/single consumer workloads and a better scalability with 8 producers/8 consumers (on different queues) for both the commits I've attached (the second one, in particular). I'm putting this for review and for validation: if anyone has a better machine to validate its behaviour is would be great. On executor benchmarks (in particular the second commit) it is much better then the original solution, but benchmarks are...just benchmarks: need to check inside the broker mechanics and workloads. A conservative approach will suggest to just use the first commit ie a simple q replacement, but I the second commit has more to offer given that would allow to use what this q offer out of the box and that seems very similar to what the thread pool was delivering in the implementation on master.
