Hi Ronald, Thanks for the response. With in the server, there is not much of a locking issues. Just to give you more insight, server is like a proxy for some of the request. All such request are delegated to an external server which may or may HTTP protocol to handle the request. Thanks, Nishi

So possibly your application depends a lot on locking? Ronald.

Apache is configured to use worker MPM mode. I have done various tests to find optimized tomcat, apache and Linux configuration for my application. Following are the machines I'm using for this load test. Machines configurations ------------------------------------ Apache Load balancer:: 2.8 GHz Dual Core , 4GB RAM Tomcat :: 2.66 GHz 2 CUP, Dual Core, 6 GB RAM There is an interesting observation when I alter my configuration to run multiple tomcat instances on same machine. My throughput increases to 2 times the original throughput if I run 2 instance of tomcat instead of single tomcat instance. I'm trying to understand this behavior as I'm not very keen in running multiple tomcat instances on same machines. Thanks, Nishi ________________________________
