TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. To update our global baseline from 2017, we want to update our priors on a few dimensions: The evolved device landscape. Hardware Past As Performance Prologue. The Moto G4 , for example. Hard Reset.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. decoding="async" loading="lazy" /> Google spent more on the SoC for the Pixel 4a and enjoyed a later launch date, boosting performance relative to the A51.

From outright misstatements about a competitor's security, to claims that performance differences in hardware show Safari is faster, to [geographic brinksmanship](/2022/02/minimum-standards/), the confident bluster hasn't gone down particularly well. This was all considered at length. And yet, Apple continued to apply stop-energy.

Google founders figured out smart ways to rank websites by analyzing their connection patterns and using that information to improve the relevance of search results. It enables unbounded scalability as more commodity or specialized hardware can be seamlessly added to existing clusters. Back in the days of Web 1.0,

After the latest redesign in late 2017, it was Ilya Pukhalski on the JavaScript side of things (part-time), Michael Riethmueller on the CSS side of things (a few hours a week), and yours truly, playing mind games with critical CSS and trying to juggle a few too many things.

— Alex Russell (@slightlylate) October 4, 2017. Our metrics at Google show a conflicted picture (which I’m working to get to clarity on). We now have everything we need to create a ballpark perf budget for a product in 2017. Maybe "ambush by JS"? 75% of of connections occur on either 2G or 3G. First Load.

On the other hand, we have hardware constraints on memory and CPU due to JavaScript parsing times (we’ll talk about them in detail later). Gatsby.js (React), Preact CLI , and PWA Starter Kit provide reasonable defaults for fast loading out of the box on average mobile hardware. Image credit: Addy Osmani ) ( Large preview ).
