[jboss-user] [JBoss Messaging] - Re: Poor performance after replacing JBossMQ

[omerlin]

Hello,

It's very difficult to treproduce as this is a big telecom project - Phonbook3G synchronization - (6 month with 12 people) - each sequencer that use a JMS selector on the shared queue launch a complex SYNCML synchronisation with an external server 

My idea was just to replace the plumbing because :
1) i found that the persistence implementation in Oracle is costly - and the implementation seems different & optimized with JBossMessaging
2) One key point on JBoss Messaging is the performance improvment

My performance test use a home-made injector (due to proprietary protocol).
-With JBossMQ i achieve around 2 req/s 
- With JBossMessaging less than 0,5 req/s ( and i get some timeout )
For information 2req/s means around 50 open session on JBoss.

I will try to give you more precise information using OptimizeIt

Is it possible that i did some configuration mistakes that could explain this difference ? (I don't see what)

rgds,
