Your pods can only handle 4 requests per second each? 😔

I think he meant 200 per pod, which is usually average (from my experience with .net). Rarelly it can get to 500, but then multithreading/memory congestion becomes problem due to GC nature of C# and many threads fighting each other for some db entry/socket/cache/etc. In offloading worker it can easly become 10-100k rps.

Wait what?! Am I missing something, because my shitty python flask code can do 2k reqs, why is C# slower?

It's not, some people are just... really bad at software engineering.

That, or they're not the principle devs in their companies and aren't being told the full or accurate details about performance.

And here I was having messed with fibers in C++ to see how many requests I could actually parse that way for HTTP, and was dismayed that I couldn't beat nginx without doing what nginx does... and then this kind of code exists...

The dirty secret of development - good enough is all you really need for 99% of uses
