Late to this thread but I'd agree with Miki :
"Speed shouldn't be in top considerations when picking a web framework. Ease of use, maturity, stability, ecosystem and otheres comes way before"
And yes in work, we work (on the HTTP python microservices) mostly with sanic (we new stuff moving to fastapi) and I really miss the simplicity and baked of solutions some things have in Django.
And yes Django having a half baked async story is a burden. But not as big as might be perceived. More and more I don't see async as a good "performance" or scaling model.
(Not recommending celery, there are good enough reasons not to use it)
