Performance:Servlets:Only When using combined JBoss/Tomcat

[johnwilson]

VERSION: JBoss-2.2.1_Tomcat-3.2.1
PROBLEM: Servlet performance
SET UP: At default recommend values

At present I am not using any feature of JBoss( that I am aware of). After moving lots of servlets from a stand-alone version of tomcat to the combined version( JBoss/Tomcat) I suffer a sever performance problem( about 20-30 time slower).

I fail to see how this can happen? Does the JBoss container wrap the tomcat container?

As far as I was believe both containers are very separate.



Thanks in Advance

Maybe all the other threads (JBoss) now running in the same VM are competing for resources/processor time.

Is the lost time spent in your servlet, or in Tomcat ?

If in Tomcat then you may be interested to try the JBoss/Jetty combo and compare results. Many people claim a real performance benefit, particularly under load. www.jboss.org and this forum are run by Jetty.

Provided that you are J2EE compliant you should not have to make any changes to your app. Let me know if you have any problems.
