Struts/JSP/J2EE performance and memory profiling and issues

Question

We are using Struts and having performance issues. And making heavy use of jsp includes, tiles, EL expressions.

I am sure this is eating up a lot of memory and processing time. What are some approaches to profile the JSP page? What tools could I use? What should I look for when profiling?

I have seen the code generated JSP Java Servlet Code and I see the bottlenecks but would rather measure it more accurately.

This is under JDK1.5 and IBM Websphere 6.1 (RAD7)

Answer 1

Is RAD 7 still based on eclipse? If yes, Eclipse has a profiler that should still be available in RAD 7. It is likely one of the perspectives available in RAD 7. Here is an article from 2006 on using the profiler in eclipse and much newer presentation (slides only) on using it from the eclipse con conference in 2009:

Hopefully the profiler tools are also included somewhere in RAD 7 as well.
