Re: Did they change the laws of Physics?
That sounds a lot like many modern websites too. Developers test them on their own ultra-fast connection with very powerful computers, but never bother to test it out on a weak computer with an slow connection. Even on my 400 meg internet with a Ryzen 7 and 16 GB of memory some websites bog down my computer when I turn off NoScript.
Google needs to test this with common settings. That means they need to test with low-end hardware and sub 5 MBPS internet. But somehow, I doubt they will. A problem with developers now -- be it Google or Microsoft or Apple or web designers -- is myopia: "It works for me, therefore it will work for everyone" or "I like the UI, therefore it is a good design" or something similar.
