The main overhead is with keeping track of and processing Filters (which
don't exist in Servlet-2.2). TC 3.3.x also has some optimizations based on
the fact that it is illegal to wrap the Request/Response objects in
Servlet-2.2. Of course, Servlet-2.3 encourages wrapping the
Request/Response :-).

Hello,
Thanks for all the great feedback so far.
Firstly, Bill Barker writes that:

Oh dear! We use Velocity, not JSP. What are the additional overheads in the
Servlet 2.3 spec?
Secondly,
Howdy,
I would add Coyote as another big change from the older HttpConnector.

Well, the big performance change in TC4.1 over TC3.3 is Jasper2 vs. Jasper1.
For heavy JSP sites, my benchmarks say that TC4.1 wins.
Since it seems that you aren't using JSP at all, it isn't surprising (to me

Howdy,
>Is Tomcat 4 slower than Tomcat 3?
Too broad of a question to answer, although in general I'd say no,
tomcat4 is faster and has been faster for every app I've benchmarked.
But from the rest of your email, your question isn't about speed, it's
about CPU usage.
