> There is absolute thresholds of usability, I don't think this is true, for slow websites (taking >6 seconds to load) the effect is mostly linear. For faster sites going from 1s to 0.5s will be less impactful than going from 6s to 3s. So there are non-linear effects from a psychological perspective, but I think those are mostly relevant at faster timescales. > difference between something tolerable and intolerable on a low end device. The only case where I have had things reach intolerable is when the network cannot actually send the data without faulting. Loading for 3 minutes is not actually intolerable. > If memory becomes an issue, excessive memory usage will lead either to: I don't think most single webpages will overload a low end systems RAM. I think the lowest system RAM you can have is ~0.5 gb usable and most sites fit within that.

So there are non-linear effects from a psychological perspective, but I think those are mostly relevant at faster timescales. I don't see how you can dismiss the psychological perspective. These are real people using the websites. If it wasn't the premise wouldn't be raised in the first place. > The only case where I have had things reach intolerable is when the network cannot actually send the data without faulting. Loading for 3 minutes is not actually intolerable. What you've had? What perspective is this being raised from? What about SPAs where you aren't loading the whole website because of lazy loading, but that lazy loading has overheads that don't include network time. > I don't think most single webpages will overload a low end systems RAM. I think the lowest system RAM you can have is ~0.5 gb usable and most sites fit within that. Could you please clarify whether you mean 0.5GB total system ram, or 0.5GB left over after system overheads. Consider this: https://gadgets.ndtv.com/jio-phone-4255 https://gadgets.ndtv.com/jio-phone-4255 or https://en.wikipedia.org/wiki/Nokia_8110_4G https://en.wikipedia.org/wiki/Nokia_8110_4G Both have 0.5GB system ram, and I can say with high confidence, having the latter, that the main system is slow, I don't believe for a second that that is somehow only bogging CPU and not using RAM. In the developing world mobile systems are often the only computing device people have, which is why there is even a market for such a lackluster phone in the jio phone. The issue, as other commenters have pointed out, is not the core website, but rather the addons that are thrown in because every marketing department and their dog needs to have their own code run on the site. No matter how simply the site is built, optimised for UI, these things will cause problems.
