Heavy traffic trouble

The jakarta tomcat too slow and go down (crashed) when my site have heavy traffic, maybe is a
regular question, but i can't found information about this problem, I am worry because i saw  the proccesors and memory performance in my system and all is ok, i have enough free memory and enough idle proccesor. I tried to fix this problem working with the thread pool information (http://www.hp.com/products1/unix/webservers/apache/techtips/tomcat.html ) but then i had the same
problem. I found information about this problem in other tomcat versions, with linux and apache, somebody known something about this problem, how fix this trouble? my tomcat is alone in a webserver, it have a connection with a Oracle database server, and the connection with my http server (is the local connection) is with the isapi filter (other ports is closed). 
I have two similar web servers with load balancing: 
I am using the Tomcat version 3.1.
my server have windows 2000 IIS with isapi filter for the tomcat 
2 x 800 MHZ processors 
1GB in RAM 
2 x SCSI 3 harddrive 
my regular traffic can be 2000 to 5000 costumer in
the same time, in other words i can have 1000 to 2500 simultaneous connection by each server, but I have problem with 800 simultaneous connection in each server.
Help me please.
excuse me and Thank you for all.

I listen about the same problem with apache and linux, but my real problem
is the heavy traffic,  I can work with FreeBSD, but, how much connection you
have on your site?

Why are you running Tomcat on IIS, if you are a Linux Admin ? Do you have
the same problems on
UNIX based systems ? I run Tomcat on FreeBSD and have stress tested it,
where as I get slow performance, it does not Crash. I have used it with
mod_jk and mod_webapp with Apache1.3 and 2. Maybe it`s more the
Server/Platform combo than Tomcat.
