i have patched jasper to use char arrays instead of strings, and it gaves a good performance improvment. It's not perfect, but is works.

The problem occurs when dealing with lots of strings. I'm attaching the benchmark, the code generated by TC, and the code generated by Resin. Resin String handling tricks ends with it making about half the amount of writes, and writing char arrays instead of Strings. I believe this is faster :-D While the benchmark is quite lame, I believe a lot of pages have similar amounts of interleaved static HTML, so optimizing this would give a healthy performance increase. (Note: I did a quick review with a profiler, and all the CPU time is spent in the _jspService method body, using a compiled JSP, so the performance overhead is in the generated code for this particular test) (I found this while looking for optimization ideas) Can we get the same kind of stuff ?
