I’m still surprised that this type of findings hasn’t had more of an impact on commercial design. It is not uncommon to find Fortune 500 sites with load times over 20 seconds. I get it that it is hard to write and maintain clean code, still, repeated studies have shown the value proposition is there.

Here is a little proof of concept I did awhile back to see how tight I could make a responsive page with a good amount of graphics. The whole page is two server calls (one is for the fav icon). It loads in about 400 ms total from github or in less than 200 from Godaddy shared hosting: https://pbskidd.github.io/cockenoe
