In particular, be aware of the difference between "fastest possible" and
"fast enough for my needs".
*Way* too many people go through the pain and agony of configuring a web
connector because they think they have to (or because people on this list
tell them they are nuts not to), when all they are running is an app with
almost no static content, or where the request rate is so low that Tomcat
standalone keeps up just fine.
My rule of thumb -- always try your app (under a representative load) on
Tomcat standalone first. If its fast enough, then you can be done
configuring things in 15 minutes instead of 15 hours or 15 days. If you
need the extra performance (or other features) that running behind a web
server provides, that's the time to invest in learning how to set the
connectors up. But not until.
