I still encounter websites/UI that are laggy on my high end workstation, I cannot image how unusable those websites would be on a low end laptop. The funny thing is, most of the time those websites have no complex requirements, it's mostly news site with things likes a covid map embed, but the map has a resolution to the meter for country boundaries... A few KB image that open the interactive map on click would work just the same. And for website with heavier requirements (web app), there are two camps, those which are excellent (like onshape, that thing is amazing, or draw.io) or painfully slow to the point I had to ditch them (notion, clickup). I have a feeling that many of those laggy website could do some key optimization to make everything order of magnitude faster/lighter.
