Async Django running on Uvicorn - multithreading issue

[musanaeem]

I was looking into Async Django, trying to find out benefits and shortcomings of using ASGI instead of WSGI server with async and sync view when i found that ASGI was creating multiple threads for multiple requests.

I set up a demo project with asynchronous functions using asyncio.sleep() to add delay. Using ASGI when i make 20 simultaneous requests for the asynchronous view, it makes 20 threads (instead of 1 thread handling the processes by setting aside the one that has delay and working on the one that is ready to be processed). I am not using any middleware or extra app that may have any synchronous code to cause this issue. More over i tried uvicorn with FAST API and it worked as expected (a single thread for async code).

According to the documentation (https://docs.djangoproject.com/en/4.2/topics/async/), "If there is a piece of synchronous middleware, then Django must use a thread per request to safely emulate a synchronous environment for it." However there is no synchronous function in my project and yet I am still facing the issue of 1 thread per request.

Here is a link to the minimalistic dummy django code I'm running using the function "uvicorn async.asgi:application --host 127.0.0.1 --port 8000 --workers 1" on a unvicorn server: https://github.com/musanaeem/Dummy-Async-Django

Does anyone know how I can run Async Django using Uvicorn such that I have 1 thread dealing with multiple simultaneous requests ?
