  | 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.
