franz1981 edited a comment on issue #26: QPIDJMS-430 Lock-Free FifoMessageQueue URL: https://github.com/apache/qpid-jms/pull/26#issuecomment-453601630 @tabish121 I haven't had the chance to measure the gains now that https://github.com/apache/activemq-artemis/pull/2467 has been merged and sadly I don't have such a fast box ATM, but I would try it and see if it can make any difference. I can surely avoid the padding even if it will lower the performance, given that it would be anyway better then the orignal version, that was locked. @gemmellr @tabish121 My only worry is that the original version was using a resizable q of messages while this version is quite strict and never grows exceeding a configured capacity ie `prefetchSize`, I hope it is not a limitation, given that it would (yield)wait on offer side until one slot became available.
