Love Django. But we are using Django with Gunicorn at work and we are having massive concurrency issues (1 process, gthread)... More than 4 concurrent requests waiting on a slow IO and the whole thing melts down...

FastAPI doesn't have those issues at all...

This is definitely something about your local setup or config. We routinely run hundreds and thousands of simultaneous connections through various versions of Django without much trouble.
