Intermittent performance problems

Intermediate performance problems are initially hard to recognize and harder to troubleshoot.   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.

How do I do so for an intermittent problem?
