    jboss/tomcat performance vs weblogic

    yuwang Newbie


      We are evaluating performance with jboss-3.2.1_tomcat-4.1.24 vs Weblgic 61sp4 using roadrunner 60 concurrent users. As we see that in most cases the response time for jboss is a little bit behind WL, while cpu utilization and paging is consistently higher than WL and also with very high spikes. The application we are evaluating is a pure WEB application. The configuration we are using is the default with maxProcessors changed to 100 for CoyoteConnector, since the default 20 simplely won't be able to handle 60 concurrently users.

      Any one can help to explain, or anyone has the similiar experience?

      Thanks for the help.

          You don't give a lot of an idea about the environment in which you are running the tests. For example, are you using the same JVM? This affects things. What is the OS? How many CPUs? How much memory? What are the heap size settings? Was the system in a quiescent state before you started the tests? Depending on the JVM, some initial GC can occur on the system.

          It is also a little unfair including JBoss if you are not using the main JBoss components - e.g. running EJB business logic. In this instance, you are not really measuring anything involving JBoss in an active sense.

          There are a few other things to consider. Tomcat is the chosen reference model. It implements quite a number of features that lends it overhead and bloat. None of the bytecode in a standard distribution is optimized. JBoss itself includes many services - enabled by default - such as the JMX services, deployment scanner, JMS and so on.

          An independent test of servlet container performance (does not include BEA due to permission to publish results):

          This should give some idea of setup for performance testing the servlet container.
