The GitHub website is slow on Safari

The Github website is slow everywhere. It is truly a piece of shit software both in terms of performance but also UX/UI and everything in between.

It's a product of many cooks and their brilliant ideas and KPIs, a social network for devs and code being the most "brilliant" of them all. For day to day dev operations is something so mediocre even Gitlab looks like the golden standard compared to Github.

And no, the problem is not "Rails" or [ insert any other tech BS to deflect the real problems ].

The problem is they abandoned rails for react. The old SSR GitHub experience was very good. You could review massive PRs on any machine before they made the move.

Well yeah, but just imagine how much money they’re saving by delivering a subpar experience!

They're not even saving any money. Syntax highlighting is a trivial workload, whereas the average SPA spends a lot of time in pointless roundtrips that have the server send more data down the pipe than the SSR equivalent.

Sending data is what’s trivial compared to compute… syntax highlighting is not trivial workload compared to that, you don’t know what you’re saying.

You say that, until you’re one of the unlucky people who discover that cloud DBs are just cloud VMs in disguise, and those cloud VMs have network throughput limits.

A fun part of a retro at my company last year was me explaining to a team, “had all of your pods’ requests succeeded, the DB would have been pushing out well over 200 Gbps, which is generally reserved for top-of-rack switches.” Of course, someone else then had to translate that into “4K Blu-Rays per second,” because web devs aren’t typically familiar with networking, racks, data centers…

Serving static files off highly efficient, distributed CDNs is a solved problem. There's no "4K blu-rays per second" when you're talking about gzipped, highly cacheable text data.

If github has a million users visiting it per day on a FRESH cache, and all of them have to download at least 10 megabytes of text data (both of these numbers are far too high), you are at ... 0.015 "4k blurays per second". Yeah I think MS's datacenters will survive.
