The obvious difference is that Tomcat 6 compilation targets Java 5 whereas Tomcat 7 targets Java 6. For a simple test JSP: Tomcat 6 (1.5) - 3,488 Tomcat 7 (1.5) - 3,530 +1% Tomcat 7 (1.6) - 3,668 +6% The 1% will be a combination of: - Tomcat 7 uses version 3.6 of the Eclipse compiler while Tomcat 6 uses 3.3.1. - the source code differences you can see in the .java files.
