"800 ms time to first load to 80 ms" It's a mistake to equivocate TTFB with being 10x faster for the user. It's clickbait. The vast majority of that speedup is not from using static files, but from putting the data on a global CDN (Amazon's Cloudfront in this case - Netlify didn't build their own.) Put it this way: if you have caching, and a page on your site gets hit 1000 times, 999 times it's going to be as fast fo…
