How to use the power of uvicorn and asgi in django?

I implemented a tiny Django app (v4.0.4) containing a REST API — GET method for retrieving some data. Next, I wanted to run the project using gunicorn+uvicorn since I saw a more benchmark performance than a normal deployment in an article. So I decided to get my own benchmark using wrk tool.

Here's what I've got:

Command Webserver Protocol Result (Req/Sec)
python manage.py runserver 0.0.0.0:8000 Django Default wsgi 13.06
gunicorn bitpin.wsgi:application --bind 0.0.0.0:8000 -w 2 gunicorn wsgi 45.20
gunicorn bitpin.asgi:application --bind 0.0.0.0:8000 -w 2 -k uvicorn.workers.UvicornWorker uvicorn+gunicorn asgi 22.17

However, the above result demonstrates something else!
Is the reason that when I want to use asgi I have to use async method instead for my API view? If so how can I change a Django REST API view to an async one? Or might I've missed some configurations?

İf you want create async rest api use one async main function and you can call another synchronous function from this function.

for example: #url.py:

path('Create',views.data_export,name='export_database')

#view.py

async def data_export(request):
  if(request.method == 'POST'):
    if(db_connect):
      system_id=request.POST.get('system_id')
      export_id =request.POST.get('export_id')  
      asyncio.create_task(start(system_id,export_id))

  return HttpResponse("Starting")

async def start(system_id,export_id):
  export_task = sync_to_async(start_export,thread_sensitive=False)
  system_id=str(config['COLLECTION_NAME']+'_'+system_id)
  await export_task(system_id,export_id)

export_task is a synchronous function.

This is how I made the rest api asynchronous.
