The memory leak issues aren't an issue with 4.1 any longer.  I don't
believe 3.3 is susceptible to this problem either, but don't know for
sure.

Thanks for the advice.  I was reading the Tomcat 4.x release notes and the javac 
memory leak concerns me because we use a lot of jsp pages.  Is that not a problem in 
Tomcat 3.3.1?  I didn't see it mentioned, but maybe I just missed it.

The features are not a huge factor.  We have to support other servlet engines besides 
Tomcat, not all of which support the new specs yet.  As a result, we can't take full 
advantage of those features until all the servlet engines we support comply.

Simple advice #1 -- try them all and see which runs fastest for *your*
application.  Nobody else's benchmark, no matter what it says, will help
you much.  (I would tend to compare just the latest 3.3 and 4.1 if you're
in a hurry, but that's more because these are the branches getting
actively maintained.)

Simple advice #2 -- "fastest possible" is not always the right goal.
Sometimes "fast enough' is just fine, especially if there are other
compensating features that make your development easier and more
productive.

Simple advice #3 -- if you need features defined in servlet 2.3 and JSP
1.2, you'll need to use Tomcat 4.0.x or 4.1.x to get them.  If your app
runs on servlet 2.2 / JSP 1.1, it will run on any of the servers you
propose to look at.
