Ready to merge 🟢

My recommendation is to remove Gunicorn from the documentation.

My recommendation is to remove Gunicorn from the documentation.

I've had some not-so-great experiences running native Uvicorn workers on production instances due to: 1-potential memory leaks on long running instances, 2-slightly lower performance, 3-and higher tendency to timeout (502) under load compared to Gunicorn-Uvicorn workers.

I think keeping it as an option is still a good thing to have, especially for long running production instances.
What do you think @Kludex?

I can proof it with measurements:

When did you do that?

Also... There's no need to prove anything here.

Hi @siavashyj

Thanks for your time and for helping us handle this topic. 🙇

Thanks for the interest @siavashyj!

I prefer to recommend the new Uvicorn with --workers, it's fewer moving parts, simpler code, and fewer chances of having errors and problems. 🤓

I updated the docs here: #12069, that should cover this.

I'll now close this one, but thanks for the effort! ☕
