I'm testing with ActiveMQ Replicated too (latest SNAPSHOT build) and seeing similar problems with stability and reliability. Performance-wise, it depends on the messaging pattern, number of pubs / subs, message size, and transaction size. Also, very dependent on network speed and local disk speed.
Can you describe your testing env? Size of messages? # of clients pub and sub? Network speed? I'm running a 3 node ActiveMQ quorum_mem and 3 node Zookeeper. Example test, 1 pub and 1 sub client running on different hardware, 4k message size, persisted messages, not using transactions, 10G network, virtual hardware box of 2 CPUs and 8 GIGs memory. ~900 msgs/per sec steady state (pub / sub running normally, keeping up with each other) -- View this message in context: http://activemq.2283324.n4.nabble.com/performance-Replicated-LevelDB-vs-SAN-tp4677811p4677995.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
