Load Testing of a Web Application

I've been stuck in load testing "heck" recently.  I've been testing the COM+ application that I have inherited as well as doing some testing on an application I have written for this client.  One interesting thing that I have found.  The load test utility I am using has this thing called a "frustration coefficient."  The COM+ app has a value of 13.  My app has a value of 0.  Smaller is better. 

Through this, I have also found some errors in my application with regards to database transaction deadlocks.  I think it is because all of these simulated users are using the same user id because these dead locks have never shown up in any user testing.  I think I am going to modify their script to use different users at various times in the application test.

Loadtesting is good.  It is helping me find errors I didn't know existed and no one has found on their own.
