Wei Zhang,
I found a forum thread that deals with Hibernate on Jboss
(http://www.jboss.org/index.html?module=bb&op=viewtopic&t=77843).
There's also a link in there to a tuning guide for Jboss at
http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossASTuningSliming.
Hopefully something in one or both of those will help you.
Eric

Subject: RE: [cinjug-users] Hibernate in JBoss vs Tomcat
What is the Xmx value for the JVM that you use with JBoss? I would
imagine JBoss would require more than the default JVM Xmx value
So could you try getting numbers by:
1. increasing the Xmx value in JBoss startup 2. getting separate timings
for getSession() and
list() to identify where the difference really lies
