YouTube videos are playing 40% faster than last year. Alex, Steven, and Rick are happy to discuss the front-end optimization techniques they used to make these improvements, and talk about:

  • Their new HTML5 framework for page navigation that enables many of their performance improvements
  • Implementing dynamic page loads with persistent content (like video players!) and dynamic prefetching, while maintaining fast server-side rendering at scale
  • Prioritizing and balancing critical network activity to start critical content faster without losing functionality
