Browsers will cache tools popular among vocal, leading-edge developers. There's plenty of space for caching most popular frameworks. The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Browsers now understand the classic shared HTTP cache behaviour as a privacy bug.

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. The Moto G4 , for example. Here begins our 2021 adventure. Hard Reset.

There is no way to model how much more traffic you can send to that system before it exceeds it’s SLA. Bill Kaiser of NewRelic published this blog in 2017 which goes some way towards what I’m talking about, but since then I have figured out a new way to interpret the data.

MB , that suggests I’ve got around 29 pages in my budget, although probably a few more than that if I’m able to stay on the same sites and leverage browser caching. There’s a trade-off to be made here, as external stylesheets can be cached but inline ones cannot (unless you get clever with JavaScript ). Let’s talk about caching.

HTTP/3 work started in 2012 with Google working on QUIC, adopted by IETF in 2017, RFC’s published in June 2022. Scalemates.com flipped the switch to enable HTTP/3 and almost immediately HTTP/3 traffic rose to ~13% of all requests on the landing page, ~49% for all pages in total. The browser stores alt-svc info in alt-svc cache.

— Alex Russell (@slightlylate) October 4, 2017. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us. We now have everything we need to create a ballpark perf budget for a product in 2017.
