Looking at the site it seems to be a (static?) HTML and shared "main.css" and "main.js" files. Both files can be cached by the browser, so it only needs to download a few KB of compressed HTML for each page. I don't think we would notice much of a difference in the navigation from one page to another if they used content preloading

It's how we used to make websites before SPA, and it's refreshing to see that it still makes a noticeable difference even on today's powerful CPUs and high speed networks.

It's also very simple and free of ads or any other extraneous clutter, a bit like hacker news, which is also fast.

There's probably a lesson in there somewhere.

Speaking of websites, does anyone know when will this land in Node? Node 24 has v8 13.6, and this is 13.8... I mean, this seems like a too big of a performance upgrade to just put it in the next release, especially since Node 24 will be the next LTS version.
