On Bernie Michalik’s Rule of Performance Testing

Two things. First my rule of performance testing is that you cannot avoid performance testing: you either do it with test data and test users in a test environment or you do it with live data with real users in a production environment.

So often I see clients try to slim down or avoid performance testing. I came up with my rule to show them that it is impossible. Now sometimes you can get away with it but it’s risky. I never advise it. You can always do some form of performance testing before you go live. Always. Still some try not to.

Second, above is an example of a site that clearly was performance tested. Even better, it is designed to respond to peak loads. Impressive.
