When you decide to improve a web-site / web app performance, it is important to first focus on ‘what’ to optimize before focussing on ‘how’ to optimize. This talk explains why this matters. It then goes into details of how to do so in a data-driven way to maximize the gains from your performance improvements.


  • Why is it important to determine ‘what’ to optimize before worrying about ‘how’ to optimize
  • How to use data to prioritize optimizations
  • How to avoid blindness to performance issues that may exist in the wild


  • Nothing in specific.
