Are they any ways to help performance on JMS

[Former Member]

I need to get as many messages as I can to go thru the JMS queues, is there any way to improve the JMS Queueing performance for PTP ?

Thanks, John

Hi John,

Briefly:

• Start the consumer before you start the producer so that the initial messages do not need to queue.

• DUPS_OK_ACKNOWLEDGE and AUTO_ACKNOWLEDGE perform better than CLIENT_ACKNOWLEDGE.

• Use separate transactional sessions and non-transactional sessions for transactional and non-transactional messages.

• Tune the Destination parameters: a smaller capacity increases message throughput; a higher redelivery delay and lower redelivery limit reduces the overhead.

• Choose NON_PERSISTENT messages wherever appropriate to avoid the persistency overhead.

• Set the TimeToLive value as low as feasible (default is for messages to never expire).

• Receive messages asynchronously with a MessageListener implementation.

• Choose the message type that minimizes memory overheads.
