Thanks for the reply. I'm using JSF, EJB3, JBoss4.2.2.GA. I have several stateless EJB deployed on JBOSS, on the same machine. I have updated now and using the local interfaces instead of the remote interfaces. Also, I have done JBoss tunning and slimming as mentioned in this link http://www.jboss.org/community/docs/DOC-10181 But there is no significant gain in performance. What else can I do to achieve optimum performance ? Thanks in advance. Farhan! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185612#...
