TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Modern network performance and availability. Hard Reset.

A 2017 study by Akamai says as much when it found that even a 100ms delay in page load can decrease conversions by 7% and lose 1% of their sales for every 100ms it takes for their site to load which, at the time of the study, was equivalent to $1.6 In DevTools, the Network inspector helps us see what the first webpage is doing too.

We constrain ourselves to a real-world baseline device + network configuration to measure progress. — Alex Russell (@slightlylate) October 4, 2017. Budgets are scaled to a benchmark network & device. For developers and decision makers with fast phones on fast networks this is a double-whammy of hidden costs.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. WebGL 2 launched for other platforms on Chrome and Firefox in 2017.
