A performance budget as a mechanism for planning a web experience and preventing performance decay might consist of the following yardsticks: Overall page weight, Total number of HTTP requests, Page-load time on a particular mobile network, First Input Delay (FID). Similarly, unoptimized images were the leading cause of page bloat.

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.
