Alex Russell explains how to build web experiences that perform well on slow networks and low-power mobile devices rather than high-end desktops.

Alex shows us the important things to focus on in performance, and how to run great experiences on slow, inconsistent networks and low-power devices.

What people say. Recommended as an excellent explanation of why mobile web performance is challenging and why developers must design for real-world hardware constraints.

On “The “Developer Experience” Bait-And-Switch”

Alex Russell first diagnosed this problem at Chrome Dev Summit in 2016 in a really amazing talk: link to this video He makes the point that lots of JS frameworks are so large that you're already doomed before you write the first line of real "app code". The framework itself has already blown your performance budget.

Note that you should not choose Ember if you are creating an app intended to be used on mobile, as it doesn't yet have code-splitting. This talk explains about why this is a hard requirement: link to this video

On “Things I learnt making a fast website”

Take a look at this talk on why mobile devices are so much slower than desktop devices ( they are indeed 10x slower in the traces I have looked at too) - link to this video Also look at the speedometer benchmark ( link ) for a more realistic comparison of how slow your mobile device is compared to your desktop when running real world apps. Here are some numbers from the benchmark from some devices - link

On “The PRPL Pattern”

Those words are meant for people who have the question "why should I go through all this trouble to implement this pattern?" That said, it is very vague. I think this presentation from Alex Russell does a much better job of demonstrating the need for progressive web apps: link to this video
