 Users often (rightly) request performance improvements to improve usability.  Developers often have ideas about code that they suspect is consuming the time, and begin to code.  But sometimes performance bottlenecks are in unexpected places that can only be quantified with detailed performance assessment tools.  These tools can also help measure the impact of code changes.
-From a user perspective the time critical functions are time to load, time to save, and time to render.
