The site is indeed instant, those performance tricks does work (inline everything, botli compression, cache, edge network like cdn), BUT the site is also completely empty, it shows nothing except a placeholder.
Things can easily change when you start adding functionalities. One site I like to visit to remind myself of how fast usable websites can be, is Dlangs forum. I just navigate around to get the experience.
Some sites can be very simple and yet quite useful. For example https://rawdiary.com/ always impresses me with its speed.

Interestingly, for me each page load takes a noticeably long delay. Once it starts loading all of the content snaps in almost at once. It’s slower to get there than the other forums I visit though.
I made a fast usable product page recently https://www.buyadagger.com/
