Ok Mark,

I can use JbossMessaging on Mysql, but my problem is with messages in memory and doesn´t with persistent messages.
Thanks

Can I do something to improve the performance of esb?

Not that I'm aware of. But that doesn't mean there isn't :)

Regards,

Daniel

Hi Daniel,

In jboss-esb.xml, if I increase the value of maxThreads (in jms-listener) can improve?

<listeners>
 <jms-listener name="nameenderecoEsbChannel" busidref="empresaEsbChannel" maxThreads="1" />
</listeners>

Thanks

Hi Claudio,

my understanding this that setting maxThreads will mean that there will be a thread pool
(in MessageAwareListener) to process pipeline invocations.

So increasing maxThreads should increase the throughput of your application.
You could also add more listeners if the receiving of
messages from the queue becomes the bottleneck.


Regards,

Daniel

Ok Daniel,

Can you (jboss team) do a profile of esb in case delivery synchronously with persistent: false? to identify the bottleneck.

Thanks

I can't speak for JBoss, but it would be interesting to have a benchmark for a non-persistent service.

This would give us an idea of the overhead of the components in the ESB, like the ESB code itself and service provider (like JMS) .

Regards,

Daniel

There is work going on to improve performance. Hopefully this will address your issue. However, it's not due for release for a few weeks.

Ok Daniel and Mark,

Thank you for information.

I have very similar problem - many messages which dont need to be presistent, and problems with performance.
I think that in VM queues should solve the problem with performance. But there is one little problem, still there are no implementation of VMQueues for jboss esb. (or i dont know about it :))

Mark - How do you see this ? When do you expect the implementation of vm queues for jboss esb ?

Mark?

Mark wrote to me some advice. You can try, in-vm queues transport from branch

There is an implementation of InVM queues but it won't be available in the JBossESB trunk until 2008.

Hi Mark, my question was about:

"Mark - How do you see this ? When do you expect the implementation of vm queues for jboss esb ?"

You already answered.
Thanks!
