Agreed. This is one of the reasons ASP.Net stole a page from the JSP book.
ASP.Net compiles at first touch to a DLL and then runs as native code (a
servlet if you will).

Actually, there's a very fundamental difference between JSP and the others.
While most other techniques are indeed interpreted, the JSP is handled quite
differently.  The first time a JSP is accessed, it is actually converted to
Java source code and then compiled to a servlet.  This is the traditional
long load time for a new servlet.

However, once that servlet is loaded, subsequent hits require no initial
startup time.  This gives JSP technology a significant advanatge in
scalability.
