I found it awful. I'm running on a very beefy development machine in the latest version of Firefox and it was kinda sluggish and very hard to read all of the information (felt like I had to scroll forever just to see a few sentences and pictures). It's also very inaccessible.

Then your "beefy" development machine is less powerful than an iPhone, since I tested it on that, and it works fine.

When I get to a full computer, I'll try it on that. I wonder if the ones I have are "beefy" enough.

Perhaps the reason for that is it’s been tested on Safari on an iPhone but not on Firefox on a fast desktop processor because the method used to animate is something fast in 1 browser but not in the other. Perhaps your comment didn’t consider that Apple’s marketing team only cater to their existing core demographic most likely already using an iPhone and not interested in the product at hand. But most of all, you didn’t bother to consider the software stack that had a huge impact on performance. And neither did Apple.

I ran it on my 2012 MacBook Pro in FF Dev Edition and it was fine /shrug

HiDPI screen alone can completely change performance characteristics of a website.

This is true. But for reference, I'm using a 2018 MacBook Pro with two external HiDPI monitors connected via USB-C (a Dell 4k and an LG 5k2k), and the page still performs flawlessly in Chrome.

Hardly a surprise that on a fresh high-end device with software stack the website authors surely optimized for it's going to perform well :P

Parent comment here, I just tried scrolling with my mouse and it was horrible. I should've mentioned I was scrolling with the arrow keys, using the mouse just now was awful and I can see why so many people disagree with my initial view. Usign the arrow keys was very hypnotic however.
