Everyone’s a Performance Engineer: How to optimize your website with the Firefox Profiler

In this talk, we’ll take a practical look at the Firefox Profiler, an open-source tool for understanding how software performs in the real world. You’ll learn how to interpret profiling data, see the difference between measured and reported performance, and discover how sampling profilers visualize what’s happening inside your application. We’ll also profile a website together and explore how to use the profiler effectively to uncover real performance insights.
