Thank you for your quick reply, I do appreciate it. I ran the testsuite again with 4 simultaneous threads (meaning 4 connections, sessions, producers, consumers), and these were the results:

However, what I didn't expect was the increase in time it suffered when just persisting. I suppose this is the disk sync bottleneck you mentioned? Considering we are using a SSD in this case, I didn't really expect there to be any bottleneck? -- View this message in context: http://activemq.2283324.n4.nabble.com/How-good-is-ActiveMQ-supposed-to-perform-tp4653343p4653346.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
