The first access is from the Sitemap compiling. It and the XSP pages can be
precompiled. Cocoon takes roughly 15-20 seconds to start up mainly because of
the number of managed resources it is controlling, and because of the compiled
sitemap. If you make Cocoon load on startup then most of the initialization
will have been done before the first request.
5 seconds is about right for an XSP page.
Keep in mind that XSP is a better match than JSP for Cocoon--there is less
translation and parsing that has to happen. By doing that you will shave off
a few milliseconds per request (10-50ms depending on size of information).
