The LCP I see is from Google PageSpeed Insights, meaning it's not benchmarked on my machine! In fact, in my setup I'll get much faster load times, but that performance level likely won't be representative of my users (I have a pretty good fiber connection till the last meter, I use Ethernet to connect, and I have a pretty beefy development workstation). The numbers you will see there aren't exactly comparable to the Lighthouse benchmarks you will perform locally: 1.5s LCP is still pretty decent, considering the average website speed nowadays, just not what I would expect from a static docs website, if that makes sense.
The page I tested is the one linked here in HN (the announcement)! I guess I should've referenced the PageSpeed Insights URL [0]. I hope you can get your bundle sizes smaller in the next versions, because honestly, from my first look (not very in-depth, of course), it's the only thing that's not very attractive about it. Likewise, I keep in mind, though, that most web frameworks nowadays ship very large bundles to achieve hydration and client-side routing.
I'm excited to see future updates to this project!
