I think Airbnb is the worst offender by far though. Instagram, Facebook and Twitter (just using your examples) operate very dynamic applications at a global scale. AirBnB is a crud app with almost no dynamic content other than the booking system. According to the first site I saw online, they process 6 bookings per second, which I could handle on literally anything with an internet connection. Of all of them, its the one I understand the least.

I thought this sounded way too low but the most generous figure I can find is 12 per second in 2022. What the hell? I thought it would be more. Should I have thought that? I guess not.

6 bookings per second at $200 per booking is $103M processed per day.

Each booking likely represents dozens to hundreds of requests. Then, for every visit resulting in a booking there’s probably hundreds of non-booking visits.

If your CRUD app's booking endpoint internally fans out to 100s of requests, you're doing something extremely wrong and/or you've dug yourself into microservice hell.

I don't doubt that they don't prcess a lot of money - that's besides the point.

They're a cookie cutter CRUD app (that happens to process a lot of money) that takes _hundreds_ of requests and 12 seconds to load on a 32 core workstation with a gigabit fibre internet connection. They have no business writing a blog on performance engineering.
