While mobile devices have come a long way in terms of network and CPU speed, many of them are still significantly underpowered when compared to desktops, especially in countries where mobile connectivity is still poor. Back in 2018 Google announced that sites with especially slow pages on mobile would be penalized. Large preview ).

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. Modern network performance and availability.

Charlie Vazac introduced server timing in a Performance Calendar post circa 2018. Caching the base page/HTML is common, and it should have a positive impact on backend times. The use of server-timing headers by content delivery networks closes a big gap. In the case of a cache miss, this should be zero.)

Each HTTP request that is required for the page needs to travel over the network and in turn this consumes energy on both the server and client. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. Show me the money!
