Migration from wsgi to asgi questions

We have a django app running on gunicorn with eventlet workers. But we are not satisfied with eventlet cause it monkeypatches everything and works badly with tooling. So we decided to move to asgi.

• I replaced gunicorn eventlet worker with UvicornWorker
• I replaced threading.local usage with asgi.Local
• For cachetools we need to use threading.RLock because cachetools is not threadsafe

And after that, we ran a load test. Seems like with the asgi server we lost about 30% of performance.

So, questions are:

• Are there any guides/docs where I can find how to tune asgi server? Anything about performance?
• Are there any docs that describe how asgi works with django? I’m not sure but looks like there is main asyncio loop and for each request, asgi runs separate thread (and it looks like I must make async_to_sync functions that do network requests)
• Is it safe/needed to use threading.RLock inside sync code or should I replace it with something?
• Should I use asgi.Local(thread_critical=True) or asgi.Local() and how thread_critical works with different code?

@carltongibson I will go to the forum with some questions, thanks. But question about performance is suitable here as I think, it’s important.

@allen-munsch No, we returned to eventlet ¯_(ツ)_/¯
