Google shows a lot of stuff about how to improve pagespeed score, but I have been unable to find any CMS (Content Management System) be it proprietary, open source or even a Page Builder that claims to offer 100/100 pagespeed (or something close to it) out of the box which seems weird to me, since these metrics are nowadays considered to be a measure of quality, regardless of statements from google suggesting that they shouldn't be so.
So, can you list a one or a few CMS-like projects offering 100/100 or so pagespeed scores out of the box?
In case you're unsure about the "out-of-the-box" term, that means in this case, that as soon as you install the platform (or create a new page), without adding any code or complex configurations, you can create a content page with it's own URL, you can paste that URL in Google's Pagespeed test and it will score 100/100 (and show your content on that URL as expected for any CMS).
Here is the link to the pagespeed test page just to be clear of what I am asking here: https://developers.google.com/speed/pagespeed/insights/
