In the usual scenario, Django is served using WSGI server (gunicorn, uWSGI are the most popular) that work in pre-fork synchronous model, hence you will need multiple workers and have a “copy” of your application for each worker. This consumes a lot of memory and drags scalability issues along with it, since one worker is busy responding to only one request at a time. Green threads are one solution to NOT rewrite your whole codebase in order to go async without bumping into threads and the notorious GIL. For the demo a simple Django concurrent application will be used and some benchmarks from a load test.
