I have been working on stress testing a Java web application (JSP+Tomcat6+Struts2+Hibernate+mysql) and well the results I was getting wasn't something to brag about! So I upgraded the tomcat version to 7, and wow! the requests/sec I got was 5 times better than before.

So enlighten me, is there this much difference between tomcat6 and tomcat7's performance? or there is something wrong with my configuration and stuff?

The Tomcat "Which Version" page includes a high level overview of the differences between different Tomcat versions. The section for Tomcat 7.x does not claim massive performance increases for Tomcat 7.x versus Tomcat 6.x. A Google search didn't offer any clear evidence either.

I'd be inclined to think that a 5-fold throughput improvement is either:

  • a Java / Tomcat configuration and/or tuning issue,
  • something a bit unusual about your web application, or
  • an unidentified artefact of the way you are doing your performance measurements.
