Hi Hardik,
what takes this time, page rendering in browser or result processing
or maybe You are talking about action processing time?
Also You can turn on profiling in struts2 to see how much time is spent where.

I had exactly the same problem with struts2. I wrote a struts2 webapp

seconds to produce the content. The bottleneck is OGNL. OGNL has an
extremely poor performance. Struts2 is an excellent framework but the

If you're accessing value stack objects via ${...} it's still OGNL under the

I would suggest you to use a profiler to find out for sure what is
