KahaPersistenceAdapter is generally faster as described. My questions are: -is KahaPersistenceAdapter as reliable as KahaDB? -does it guarantee persistence of queues? I do not need Topic durable subscriptions, only guaranteed delivery for queues -enableJournalDiskSyncs="false" speeds up KahaDB a lot, but, does it guarantee persistence of messages in all cases? Thanks, Carlo -- View this message in context: http://activemq.2283324.n4.nabble.com/low-persistent-messaging-performance-using-kahadb-tp2367478p3037432.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
