Kirdorffer,
Thanks for your message. I assume the JSP preprocessor has to generate Java
code using servlet in a fairly generic way. It is like the performance different
between C++ and assembly. If you hand write assembly, you probably has higher
performance. Nowdays, however, the different between C++ and assembly is not
great for most applications, so people choose C++. Is it true that the JSP to
Servlet compilation is so simple that performance difference between JSP and
hand written Servlet is very minimal?
