Dear J'
What do you mean you are hitting connection limits?! Are you getting
errors? What are you seeing that makes you think that is slow?
Is there a database involved in this application?
I assume you are running linux on your server, with a 2.6 kernel.
run the following commands while your box
1) ps auxH
2) ps auxH |grep -c java
3) vmstat 5 5
4) iostat 5 3
Then we will have a bit of an idea what is going on.

The reason it is hitting its limits is easy: traffic. We easily
get enough
website traffic to overflow the connection limits unless I have
many boxes
available to serve. I know these can be configured to handle more
connections. I know that we should be able to do this in the tomcat
server. That is why I need those tweaking parameters defined.
Thanks,

First you should investigate why tomcat is hitting its limits.
Why do you think it does? Which resource is the limit?
Do you have/use any monitoring software? moskito? lambdaprobe?
tomcat-manager?
