ASGI Server in Development?

See the docs for How to use Django with Daphne - there’s a section in there about its integration with runserver.

Side note: If you’re using Windows in either your development or your deployment environment, you are likely to face performance-related issues. Daphne/Twisted and Windows apparently don’t “play nice” together. (See this thread for a recent example: Django Channels with Redis slow intialization)

I have only ever deployed Daphne to Linux and have never faced any performance-related issues. Everyone I know who have tried to deploy it to Windows has faced some type of problem.
