My phone is literally struggling to even scroll through this page.

Half the reason I keep my mid-range 2018 Android phone as a daily driver, is as a litmus test to see how poorly-optimized a website is.

And this page is a very poor sales pitch in that regard.

And the result is total frustration, because everybody else is designing on their M2 Macbook, so everything is frustrating to use.

I have an entry-level iPad from 2018 that crashes on most media-heavy websites, though I also blame Apple because it is obvious that every iOS release uses more and more RAM than the previous one. CPUs don't get slower as they age, but it certainly feels like it!

My phone is middle-tier but it is new. This website has probably the worst scrolling performance I've ever seen while using this phone. Can only imagine the dozens of megabytes of JS it is downloading once the "zero-JS part for SEO" is done.

Even on my Macbook with Firefox the site has a strange feel when scrolling. It's not exactly struggling but it feels unnatural and slightly off/slow/uneven. Like it's on the edge of struggling. Bit hard to describe. The effect gets worse towards the mid section of the page with the side scrolling logo circles. I removed that section via dev tools which helped with performance. When I have that part of the page in view I get 80-90% CPU usage of one core. But even after removing it I can saturate a core by scrolling around, especially towards the lower part of the page.

It is indeed one of the worst optimized CSS I've seen in a while. Weird for a project that is all about speed.

Yes I came here to write that it scrolls atrociously. If people take the hint that this is how an Astro site performs, oops!

The docs site from the Get Started link scrolls fine.

Weird, for me it scrolls perfectly smoothly on Brave/iOS Iphone 8. I wonder where the difference lies ? (I intend to use Astro, so I'd better know beforehand)

Same. Very ironic given how hard they're peddling speed.

I noticed the same, what's going on? Too much complex CSS?

It doesn't even smoothly scroll on my desktop.

I have a phone from 2017 and I can't say this scrolls any worse than hackernews does. Certainly no issues on my new phone.

I noticed the same on Firefox mobile, but Chrome worked better
