When we look back over the history of web performance we see a heavy focus on reducing the number of requests and getting files to the browser quickly.

In short we need to deal with not just how quickly our sites and apps load, but also how quickly they run.

In this session we are going to take a lightning tour of how Chrome converts the DOM into pixels, see how our code affects its workload, and arrive at a modern workflow for finding (and eliminating) rendering bottlenecks.
