The resource loading waterfall is a cascade of files downloaded from the network server to the client to load your website from start to finish. It essentially describes the lifetime of each file you download to load your page from the network. It is important to note how much data the client needs to download.

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.

For a busy page with lots of external resources (like perhaps a news website with loads of ads and trackers), there might be dozens of DNS lookups required per page. This typically happens once per server and takes up valuable time — especially if the server is very distant from the browser and network latency is high.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. Websites would magically become 50% faster with the flip of a switch!
