You’ve measured the performance of your site using developer tools on your computer. But what do real users see when they go to your site? Ben Maurer discusses how Facebook pieces together data from multiple sources—load balancers, CDNs, HHVM, resource timing, navigation timing, etc.—and uses it to make a fast site.

Topics include:

  • How Facebook’s site works: a brief overview of what happens when you type into the browser, how Facebook incrementally renders pages, and what metrics it cares about
  • What data sources you need to understand performance: the types of performance measurements Facebook makes and how it fits them together to provide a cohesive picture of what its performance bottlenecks are
  • What Facebook has found: real-world examples of problems and fixes Facebook’s tools have found
