If you’re optimizing for the Web Vitals , you might be interested to hear that images account for ~ 42% of the Largest Contentful Paint element for websites. Assuming encode/decode speeds meet your needs. Encode/Decode Speed. This is why a lot of our guidance on performance talks about image optimization.

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.

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. When a website has a prefetch link, the browser will silently download the content and store it within its cache. Data-loading patterns are one way you can optimize your applications’ speed.

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.

Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. Finally, not inlining resources has an added latency cost because the file needs to be requested. Even if a server supports HTTP/3, however, clients (and website owners!)
