| So your persistent message throughput will entirely depend on how your Oracle box is set-up tuned etc. Oracle is very tunable however.
For persistent messages in the AUTO_ACK mode, you are limited by your hard disk performance. The database has to perform sync writes per each message, so I doubt Oracle has any advantage/disadvantage in comparison to other databases.
But, what about non_persistent messages ? In the current JM implementation non_persistent delivery performance seems to be determined by the relational database backend too as I wrote earlier, though it does not suffer from sync writes as much as persistent delivery does.
