Hello I am currently evaluating performance and reliability of ActiveMQ 5.8.0 and LevelDB with Amazon AWS EBS volumes and provisioned IOPS, using the activemq-perftest plugin. Message persistence is of primary importance for my client. When I run my tests with the broker, producer and consumer, I see very little disk activity (vmstat output blocks). When I run the broker and producer only (no consumers), I see the expected disk activity/output blocks.
I'm assuming that the messages are not being persisted in the first scenario because of the presence of the active consumers. Is that correct, and if so, is it possible to disable this behaviour? I see that using KahaDB as the persistence adaptor, this feature is managed by the concurrentStoreAndDispatchQueues parameter.
