I agree, I have an inhouse portal which is accessed by a few hundred
people constantly because it is their main entry desktop, to the whole
intranet. It is fast, with the occasional GC hickkups.
The most likely thing is a performance issue either in the app or db layer.
The most likely possibility to resolve that issue is to increase ram,
check the access algorithms which go down into the db layer, check the
db layer for performance problems and add caching if needed (good db
layers should handle that themselves)
The thing is, if you have 500 people accessing a site, you do not get
too many hits at the same time, it serving the data should be a no issue
for tomcat, it can handle bigger loads, and most likely the main problem
is application specific and even more likely database specific.
I do not thin that extensive clustering would help in this case.

IMHO most tuning potential is in the code of the developer rather than in
the servlet container.
Use DBCP and avoid looking up contexts and datasources all the time but
simply return these from a "utility database class". If possible cache
data rather than update this upon each request (for instance user settings
and authorization, dates and other distinct common values to be shown in
combo boxes, ...)
That being said Tomcat of course may take a performance hit when GC kicks
in so to finetune the Tomcat settings use a profiler to investigate it
while running and change thread no., size etc. as well as JVM parameters accordingly. Further you may want to disable automatic recompilation when
JSP changes as well as precompile your JSP.
