3. Performance Workflow hypothesis measure investigate stress the system change experiment
4. Things that I did wrong… • Didn’t clearly identify the goal (﴾or at least didn’t stay on track with the goal)﴿ • Not enough stress on the system • Too much noise in the measurements from the rest of the application to notice subtleties in the data • Skewed measurements by only looking at the case it was designed to work well for • Didn’t measure the full system
5. …but fixed in a later iteration • Concrete goal • Create a separate benchmark app and measure in real life scenarios (﴾in the real app)﴿ • Put the system under heavy stress • Look at cases where the system would reasonably perform poorly • Profile the whole system
