I have been doing performance testing and have identified the StrutsRequestProcessor as a bottleneck. Has anyone else seen this or found way to improve performance. I know it is doing a lot of stuff (probably using reflection), but just wanted to get some feedback.

Just make sure you profile correctly:
example in optimize it:
-don't count wait times: any blocking thread time should not be counted.
-don't profile by instrumentation, it is hell slower and also bias most result (ratios gets skewed and what shows as 80%-20% may actually be 50-50). Instrumentation is good for invocation count, mostly.
-Profile by sampling: it also gives you what line was slow. Much better. And much less intrusive, but no invocation count.

Are there any statistics you can show the performance is slow?
Maybe you can start by giving a testing scenario, your machine's capabilities, etc?
If such a statistic was available, it can be submitted for the creator's reviewal and correction.
