As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks. If your average visitor is on a fast cabled or cellular network, they probably won’t benefit from the new protocols all that much. An often used metaphor is that of a pipe used to transport water. Congestion Control.

But pages keep getting bigger and more complex year over year – and this increasing size and complexity is not fully mitigated by faster devices and networks, or by our hard-working browsers. Having said that, looking at data over the past ten years, it's safe to make the observation that pages are definitely trending bigger.

Google uses anonymized data from Chrome users to feedback metrics and makes these available in the Chrome User Experience Report (CrUX). CrUX data is available in a number of tools, including in Google Search Console for your site. That data is what they are using to measure these three metrics for the search rankings.

A cluster is just a pool of compute resources available to a customer’s applications. The pool of resources, at this time, is the CPU, memory, and networking resources of Amazon EC2 instances as partitioned by containers. The agent is written in Go, has a minimal footprint, and is available on GitHub under an Apache license.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two.

Yet, this criticism of React isn’t completely unwarranted: React and ReactDOM total about 120 KiB of minified JavaScript, which definitely contributes to slow startup time. When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware.
