Performance slowdown on JBoss 4.2.3.GA

[vink]

I've migrated my product from JBoss 4.2.2.GA to JBoss 4.2.3.GA.
I'm using Remoting 2.4.0.SP1.

I realized that performance is terribly slow in this version. If earlier a rmi call was taking 100 ms, now it is taking around 200 ms.

Please remark, what has changed in JBoss which has caused this adverse effect? I'm just making use of the specified version of remoting.

Forget to mention one thing,
I was running "default" configuration in JBoss 4.2.2
whereas "all" configuration on JBoss 4.2.3.

I'm not aware if anything in that configuration can cause this behavior.

Hi Vinay,

Have you made any progress with this issue?

Of course, if you're using the same version of Remoting in both cases, I feel fairly safe in assuming it's not a Remoting problem. Of course, you never know.

When you say "rmi call", which particular subsystem are you talking about. EJB3, for example, or JBossMessaging?

Hello Ron,

I've measured latency of calls going to SLSB in JBoss with "default" & "all" configuration. The difference is terrible.

I'm not aware what can cause this performance bottleneck in these two configurations so far. (have not invested much time in it, thought I got some reply from your end as I've not designed JBoss.)

Hi Vinay,

That's a very interesting finding, and I don't have a clue what could cause the slowdown. Could you start a thread on the EJB 3.0 forum http://www.jboss.org/index.html?module=bb&op=viewforum&f=221 and see if any one there has some ideas? If you do, could you post on this thread a pointer to the new thread so I can follow it?

Thanks,
Ron

Thanks, Vinay. I put a watch on that thread. Hopefully we'll get to the bottom of this issue.
