Quite a lot, actually. I went to the NY Velocity conference back in 2014, and these are from my notes. Unfortunately, I don't have any sources to link back to, except I believe this was the session where my notes came from: https://conferences.oreilly.com/velocity/velocityny2014/public/schedule/detail/36041 https://conferences.oreilly.com/velocity/velocityny2014/publ... Also an obligatory warning that correlation is not always causation. - Walmart.com: for every second improvement in page load time they experienced a ~2% conversion increase. - Shopzilla: sped up pages from 6s to 1.2s, increased page views by 25%, increased revenue by 12%. - Yahoo: increased traffic by ~9% for every 400ms of improvement - Mozilla: made pages 2.2s faster and resulted in 60m more downloads. - On average ~57% of users will abandon a site that hasn't loaded in ~3 seconds (again, I don't know the source). - When a page loads at ~8 seconds , conversion rates start to drop by 40-60% (and again, I don't know the source). - In a 2012 EEG study (sorry I don't know which one), they throttled a desktop connection from 5Mbs to 2Mbs, and found that about half the participants had difficulty concentrating and finishing the task asked of them. - From 2013-2014, the median page size has grown ~67% in just a year. About 50-60% of the size is from images (again, I don't know the source).

I get what you are saying. My doubt is because most businesses are not Walmart (etc). What matters at the scale of a large retailer (so large as to dwarf Amazon) is not what matters at most places. It's not just that Walmart is dealing with fungible goods, it is also that: + Walmart's online store is dealing with legacy pre-internet database architectures on the back end. + Walmart's online store is competing with Walmart's brick and mortar stores when it comes to architecting IT infrastructures and allocating resources and the brick and mortar stores eclipse Walmart's etailing. Because I think Yahoo is pretty good due to being consistently profitable, I will forgo the softball snark of "Why would a tech company want to be like Yahoo?" But there is really question of whether the best practices of the companies you list are appropriate for a business in a narrow market. Going further, if it is an area of concern choose technologies and page architectures that don't run the risk. Angular and React are developed to meet the needs of companies at the scale of Google and Facebook not a shop where the collective knowledge does not include experts at page repaint metrics.
