    Bad performance after migrating to JBoss 5.x

      Hello everybody!


      I've experienced really bad performance after migrating our application from JBoss AS 4.2 to 5.0 or 5.1. After migrating to JBoss 5, JSF requests take about 3-4 seconds (600-900ms on JBoss 4.2)! There are no errors or hints in the JBoss log and the application works as expected (except for the really bad performance). The application makes heavy use of EJBs and JPA (requests without invoking EJBs are also very slow). I found out that a JSF only application without Seam runs quite fast.


      I've searched the JBoss AS forums and found a lot of similar topics about that problem without a solution for that problem. However, all these threads have one in common - we all use Seam. I've tested my application with Seam 2.1 as well as with Seam 2.2.


      Is that a known problem with JBoss AS 5? Anybody knows the cause of this problem?


      Thanks in advance!
