I personally find it neither surprising nor disturbing that Tomcat 3.1
is slower than competing products right now.  Tomcat is a very
new project, and as with any new project, the first focus is on
stability and features.  Once the system generally does what people
need it to do, the developers can then move on to improve performance.

Given the number of people using Tomcat, performance will improve.
I'm comfortable with that; upgrading versions of Tomcat in the
future will be much easier for me than switching between very
different servers.  If you're building a new site and
expect to spend your first year building traffic, then Tomcat
might be a good choice; by the time you need it, Tomcat's
performance will be much better than it is today.

The best thing you can do to help is to use Tomcat, understand
how it works, and pass your suggestions (and fixes if you can)
back to the Tomcat developers.  Open-source projects thrive when
there is an active base of user/developers.  Right now, it appears
Tomcat has a real need for people to work on documentation, so
if you think you understand how to use Tomcat, volunteer to write

Also keep in mind that Apache is somewhat unique among open-source
projects in being significantly faster than most of it's commercial
counterparts.  Since Tomcat is the reference implementation, it will
probably have to focus on features and portability, sometimes to the
detriment of performance.  It's quite possible that commercial
servlet engines will always be somewhat faster than Tomcat, although
that margin should shrink considerably once Tomcat is past its
