Too hot to handle - optimizing for low powered devices

We know what web performance is—getting pages to render fast for as many customers as possible. Traditionally, the focus has been on the network, improving the time to deliver critical content, but the combination of modern web applications, better network connectivity, and HTTP/2 is reducing the impact of the network on site speed. Our next great challenge is how well our applications perform on our customer’s CPU. As our dependency on the CPU has inevitably increased, our devices have gotten smaller, and processors have struggled to keep up with Moore’s Law. Meanwhile, our ability to profile and analyze the CPU footprint of our web applications has barely improved beyond the timeline in Chrome’s Developer Tools.
