Making fast apps and services that scale to millions or billions of people is no simple task. Dealing with the impact of poor performance can be just as challenging, and can be measured in slow user experiences and inefficient infrastructure. History is littered with examples of projects that failed to maintain their performance as they scaled. No two performance problems are ever quite the same, but there’s a lot we can learn from one another as an industry.

On February 24, 2016, hundreds of engineers came to Facebook’s Menlo Park campus for Performance @Scale, an all-day event dedicated to making technology fast and efficient. Speakers from Facebook, Google, LinkedIn, Microsoft, and Netflix came together and covered topics such as low-level system profiling, production measurements, regression detection, efficient triage, and more.

Videos and talk descriptions from the event are posted below. If you are interested in joining the next event, please check out and follow the @Scale Facebook page.
