Life of a web request: TCP, HTTP, SPDY, Mobile and Navigation Timing
Part one covers much of the underlying networking infrastructure, which you may not think about day-to-day, but which often dictates the delivery and consequent performance of your application:

• What is the impact of slow sites?
• What is "fast" and how are we doing today?
• Life of an HTTP request, TCP-up
• Faster networks will save us, right? (Mostly) Wrong!
• Bandwidth doesn't matter (much)
• HTTP 1.0/1.1 and TCP performance
• SPDY in 10 slides, or less
• Performance of Mobile networks
• Under the hood of Chrome's network stack
• Navigation Timing & Real user measurement (RUM)
  

Life of a webpage: DOM, CSSOM, rendering, acceleration
Part two

picks up from slide 79 and is focused on the architecture and the execution model of the browser:

• Tokenizing, parsing, and construction of the DOM
• Building the Render Tree (DOM and CSSOM)
• Measuring visual & rendering performance
• Hardware acceleration 101
• Putting it all into practice on a synthetic example
• Critical Path analysis for guardian.co.uk
• Performance rules, tips and tricks to apply on your site
