[jboss-user] [Performance Tuning] - jboss messaging falling over during load testing

Busy load testing an application that makes use of jboss messaging. When performing load testing, it seems that messaging seems to be the bottleneck in performance. Using 2 queues, configured to be clustered, and messages are non-persistent. the persistence service is mysql (DefaulDS = mysql over network). What parameters would help improve performance? My assumptions would be: change persistence-service to local hsql. DefaultRedeliveryDelay - change from 0 to 1. is 0 immediate? 1 = seconds or ms? Would MessageCounterSamplerPeriod affect performance? The server is currently running as a single node on the partition, but will be clustered.
