    Another great show.  One thing I would like to know is what good sources are out there for learning about defining useful performance metrics. 

    As was stated in the show, the only thing you usual get is something like "it can't perform worse than what we have now."  On the surface that isn't directly measureable.  You can go back an look for statistics on the current system, but does the statement even reflect the true requirements?

    Any suggestions?

    As I said on the air - I believe there are 4 dimensions to good performance metrics

    1. Response Time
    2. Throughput
    3. Concurent Users
    4. Data Bandwidth

    If you can define performance metrics that accurately describe these 4 dimensions you will have a good testable metric. For a really good discussion on this topic make sure you take a look at the chapter titled "Performance Modeling" in Improving .NET Application Performance and Scalability.
