"The top-line takeaway is chilling: sites that are explicitly designed as SPAs, and which have intentionally opted in to metrics measurement around soft-navigations are seeing one (1) soft-navigation for every full page load on average."

The Performance Inequality Gap, 2026 - Infrequently Noted

Embedded in this year's network and device estimates is hopeful news about the trajectory of devices and networks. It has never been easier to deliver pages quickly, but we are not collectively hitting the mark. Indeed, the latest CrUX data shows not even half of origins have passing Core Web Vitals scores for mobile users. Browsers will need to provide stronger incentives. This will be unpopular, but it is clearly necessary.

RE: toot.cafe/@nolan/1156227060694

Those of you who are not web devs (good choice) may not quite appreciate what this means.
You know how websites are loads slower now, and don't work without JavaScript? Well, one of the big (dubious) arguments made in favour of this transition was that you download a bunch more code first, but then it'll make everything faster once you're there. It's front loading.
What @slightlyoffAlex Russell has shown is that this is not relevant, because people don't stay on the sites long enough to get the benefit.
