What's your opinion on Google pagespeed tool?

Hi everyone,

Recently I’ve stumbled upon a fact that it’s very hard to get 99 in google pagespeed for a website


For example, you can test https://thoughtbot.com/

Google says
Eliminate render-blocking JavaScript and CSS in above-the-fold content

But even if I move everything except 1 css file to the bottom of the page, score remains the same.

Some people write about including some critical css in head. And using tool like GitHub - addyosmani/critical: Extract & Inline Critical-path CSS in HTML pages or GitHub - pocketjoso/penthouse: Generate critical css for your web pages ( both for NodeJS ).

My question: “Is there any solution for this in Rails world? I can’t find any.”
