Github user franz1981 commented on the issue: https://github.com/apache/activemq-artemis/pull/1793 @clebertsuconic @RaiSaurabh @michaelandrepearce **Re performances** I've the first results using just a small benchmark with 1 producer/1 consumer using 100 bytes messages. ``` this PR: 37050 msg/sec 2.5: 85689 msg/sec ``` So performance-wise there is a long way to go, but I think it is related to some correctness issues. **Re correctness** I've launched a run on CI just with the OpenWire test suite with no success: ``` [INFO] ActiveMQ5.x unit tests ............................. FAILURE [ 2.950 s] ``` So I've decided to run the most some on my box@home. The results from `org.apache.activemq.artemis.tests.integration.openwire` ones shows 7 failed tests/341: ``` CompressedInteropTest.testCoreReceiveOpenWireCompressedMessages MessageListenerRedeliveryTest.testQueueSessionListenerExceptionDlq OpenWireLargeMessageTest.testSendReceiveLargeMessage GeneralInteropTest.testSendingToCoreJms SimpleOpenWireTest.testTempQueueSendAfterConnectionClose RedeliveryPolicyTest.testRedeliveryPolicyPerDestination RedeliveryPolicyTest.testDLQHandling ``` I've to run the `tests/activemq5-unit-tests` yet but I suppose that's enough to be fixed. Sorry for letting this PR sitting here for such a long time and thanks @RaiSaurabh to have worked on it: I think that given the right direction taken by the work on this PR makes a lot of sense to fix all the compatibility issues first, before looking to the performance gains that in the current state, are not present. @RaiSaurabh don't give up with the hard work done here and take a look at the tests results: as much as possible I will try to help by reviewing the code and propose fixes :+1:
