And even more - it shows the tomcat overhead ( how much time is tomcat
adding to each request ) - and it can be used to find other "timings" -
for example a servlet that does getParameter() or getHeader() or a
dispatch.

The dispatch time is very important ( and it allows you to make decisions
about the way you design critical pieces of your software ) - and to find
it you need the time of a servlet doing a number of dispatches minus the
tomcat overhead ( that you got from HelloWorld ).

It's not an exact science, but it's not just a random thing, without any
value. Your app response time can be estimated - at least the lower
bounds, based on what your app is doing.
