We have been running our app on JBoss 4.0.RC2 using EJB.
 
We have now migrated/upgraded to JBoss 5.1.0.GA and use EJB3 with annotations.
 
The problem is our whole system seems to be running *considerably* slower in the new JBoss. We've added timestamps in our code to messaure certain methods and it seems almost everything is running from 2-3 times slower in the VM.
 
Anyone have any idea what could be the cause of this? Is it just that 5.1.0.GA stinks? Or is it that we need to change some settings or similar?
 
This slowness is not acceptable for our app.
 
Any help is very much appreciated!
