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 @slightlyoff has shown is that this is not relevant, because people don't stay on the sites long enough to get the benefit.

@sil @slightlyoff I remember when this was a desktop problem that nobody wanted to talk about. Add a splash screen to cover the enormous setup time, then any instrumentation shows that the user usually closes the thing in seconds.

Yet another case of the same people who scream "you can't improve what you don't measure" steadfastly refusing to measure anything that might impact how they do things...
