performance problem

[JE...@mb.bluecross.ca]

I have an apache/tomcat environment that is experiencing performance 
problems.

My production environment has apache on one win2k box, and the two tomcat 
instances on another win 2k box. 

When I load test the my application directly against either of the tomcat 
instances, I get about 150 req/s. When I test with apache in front, I get 
10 req/s. This was with apache server temporarily placed on same network 
segment as tomcat box.

I recreated the production setup on a couple of developer workstations 
(slightly slower hardware than the production environment), and got > 70 
req/s.

Apache and tomcat conf files are essentially identical in both 
environments.

Does anyone have any clues?

Hmm...
http://www.greenfieldresearch.ca/technical/jk2_config.html

Reading that, look for the one line in red font.  Seems there's potential
config problems when apache and tomcat are on separate boxes, as they need
to share a file. You'd think this would prevent operation, rather than
slowing it down , so perhaps it's not related.
 
We use similar architecture, but JK (which doesn't seem to require that
shared file).
