> I deal as DevOps/SRE daily with these services, and finding one that will do a first load under 10s is close to impossible

I am currently in Indonesia on extremely flimsy and slow wifi at 1-2 bars that maybe tops out at 50mbps on a good day if no one else is on it and the gods align to grace me with a decent speed. Day-to-day, it's around 25mbps.

Doing a hard refresh of Linear (not affiliated in any way other than using them for work, but I know they use React), a complex project view that includes many graphs and other things like that, the full load time for everything on screen is 5.6 seconds with ~15MB of content loaded (this includes images and interactive graphs). DOMContentLoaded finishes at 360ms and the full interactive load is finished at 600ms, with me being able to click on tickets and navigate to them at the roughly 1s mark or less. Back home Linear load instantly for me with full interactivity, and the cached version of it even here in Indonesia is similarly fast.

It's not the frameworks slowing things down, it's usually all the bullshit that the business forces on its users that the devs have 0 say over. The app I work on loads really, really fast on dev builds that don't have any of the idiotic tracking BS enabled (for example on staging builds, which aren't even fully optimized builds compared to regular prod builds), but because the marketing, data and sales teams want their google analytics and 7 other tracking softwares, the whole thing slows to an unbearable crawl as we load in dozens of MB of packages each bigger than the Vue library controlling the whole thing.
