      I would expect mobile first design to result in significantly lighter pages, since you should need less HTML/CSS/JS to "fill" a small screen

      But the trends are in the opposite direction. Does Retina offset that effect, or do mobile-first pages end up fatter for some reason?

      Does mobile-first benefit from JavaScript frameworks / SPAs, or is it hurt by them?

      @simonw People blame JS, but even with heaviest SPA framework bloat, client usually pays perf cost once, likely smaller than one big photo.

      @wilsonminer @simonw this is a misnomer—not all bytes are created equal: JS loads differently and has more performance impact than images.

      @zachleat @wilsonminer true, JS is more likely to block page rendering + there's additional burden (esp. on mobile) of parsing/executing it

      @simonw @zachleat @wilsonminer : none of these SPAs cache aggressively enough today. They could adopt SW though; near-instant starts

      @simonw @zachleat @wilsonminer : in fact, in our work w/ partners so far, SPAs are often easiest to take to offline-first architecture

          @simonw @zachleat @wilsonminer : chrome, opera, and soon FF, but it's progressive. You can adopt now and benefit more over time

          @simonw @zachleat @wilsonminer : it's heartbreaking to see sites like Medium that *do* have SPA arch leave all this latency on the table
