I don't know how they perceive the performance. I see 41 network requests. That's 2.1 MB of CSS over the wire, blocking rendering and hurting painting and loading speed. There's 400 KB of Tailwind, 87 KB of general CSS, plus another 200 KB of other general CSS. They need to embrace functional CSS properly. I'm sure they could have a single CSS file under 80 KB that renders everything.
These type of comments often come from a place of arm-chair reasoning where you might not sit on the experience of working hands-on in a large team on a large product. While it’s probably true that X kB sufficient, that amount of performance optimisation is usually not warranted at this scale. Maintaining a design system, working with scoped classes, legacy code, and dealing with the complexities of chunking and probably further challenges we are not aware of from the outside. It seems like a common sentiment on HN (maybe not you in particular) is that engineers should drop everything and work overtime on optimizing performance, when it comes to web apps
Isn't this backwards? Optimizing assets becomes more important with scale, not less. Not saying it is actually prioritized that way or that it would be easy but IMO the more traffic you have the more important it is to be frugal with bits.
Yeah. Sites like GitHub pay a lot of money every month for servers. At scale, a bit of performance work can save you millions on your bills. And make your site run faster for users at the same time.
