Wondering how much it matters: initial load of page

Background: I found that when I accessed the home page of one of the apps our team was working on, there were around 1000+ requests and over 10MB transferred in a span of 10 minutes (and it was still going). On screen, what’s visible is just the login page.

After they’ve fixed it, I went ahead and checked our current apps in the test environment. Just a disclaimer though — I’m not a performance tester and I just gathered the info I got via Chrome Dev Tools.

3.6 MB and all that’s visible is the login page?

That prompted me to then google what’s the average out there. I’ve come up with a bunch of interesting results that’ll most likely make up my weekend reading:
