There's no full profiling path yet - this is something I hope to work on as we start integrating ASGI code at work early next year.

400ms for a request is already very long; I'm slightly concerned by that (unless that's normal without Channels installed as well).

If you want to do a basic profiling test, you can just write a very basic consumer that sends something onto the reply channel and then:

1) Directly inject requests into the channel layer from a python script, listen for the response, and time the roundtrip. You can import `channel_layer` from your project's `asgi.py` - if you don't have one the docs talk about how to make one. You'll want to call channel_layer.send("http.request", {"reply_channel": "http.response!test", "path": ....}) and channel_layer.receive_many(["http.response!test"]).

2) Directly make HTTP requests on the server running Daphne to it via localhost with a similar round trip measurement. Something like `ab` works well for this; remember to either target a very simple view or compare it with a similar test using a WSGI server.
