Hi Peter,
That is why I mentioned it. We deliver our static content from other
servers,
and had originally considered hiding our TCs behind apache for
'security reasons'.
After seeing the speed difference, and the fact that their isn't
really a security
difference if you just push all the
tests stressed only light JSPs or a real site ?
and what is your solution for load-balancing/failover ?

We did some comparisons between running Tomcat 5.0 standalone, or TC
5.0 and Apache 2.0
If you are ONLY delivering JSPs, we found that we could only deal
with 50% of the requests when running combined Apache TC and mod_jk

Using the worker-mpm or fork-mpm, apache does the same nasty thing with
threads and keep-alive, although I believe that when its starts running
out of threads
it stops offering keep-alives - and to make matters worse - for each
connection
you now have 2 threads - one for apache and one for tomcat

I would also consider turning of keepalive. Unfortunately tomcat (and

Hi Anand,
We currently have a similar problem. Under load the JVM consumes more and more
memory. (We are using tomcat 5.0 and Sun JVM 1.4.2 and linux (debian sarge))
In our case it looks as if the Garbage Collector is not getting enough time to
free memory - but this is still very much a guess.

Hi Peter,
I am not using keep-alives to keep session persistence, but was rather

a tcp connection for each request - and thereby saving 3 tcp packets
