The first thing to recognize is that chaos theory and perfect storm scenarios do happen: these are generally timing related. As an example, the garbage collection occurring during high volume usage on a system running reports and a virus scan starts. ---++ Recognizing that you have a problem Because intermediate performance issues can be hard to consistently see, there are several tactics that have to be performed in order to understand what scenario actually exists. Specifically: * Consistency * Timing * Severity ---+++ Consistency Consistency is important for reproducing the problem. One instance of occurrence is sometimes once more than practical.
