  At the scale of the sites listed, it probably matters. But those sites have the traffic volume to run A/B tests at statistically relevant scales and have probably run A/B tests against page content to have already picked up lower hanging fruit. Or to put it another way, the BBC website is much further along the "first make it correct then make it fast" curve than most websites.

    Ya I get what you're saying. Buddy of mine made this barebones calculator that allows you to see the kind of monetary impact any site could expect when working on performance: https://wwwillchen.github.io/web-perf-budget/ https://wwwillchen.github.io/web-perf-budget/ It's still a prototype and missing a lot of explanation, but the numbers behind it are solid.

      I'm not sure that there are generic numbers. Some things I will wait in line for, other things like gasoline at the filling station I won't because I can get it somewhere else. The same is true with ecommerce, it depends on what I am buying and where else I can get it.
