Could it also be that servers resources in general are lower and that there are more clients/instance than before? With all this virtualization, Docker containers and really cheap shared hosting plans it feels like there are thousands of users served by a single core from a single server. Whenever I access a page that is cached by Cloudflare it usually loads really fast, even if it has a lot of JavaScript and media. The problem with JavaScript usually occurs on low-end devices. On my powerful PC most of the loading time is spent waiting for the DNS or server to send me the resources.
