I have used org-mode/babel as a notebook replacement, and obviously the flexibility and the editing capabilities are vastly superior to Jupyter notebook, but I fund it sluggish. I assume that, at least in my setup (using babel-python), the kernel is invoked synchronously. I also didn't try to get any form of completion working, but it should be possible and it would be nice to have.

What is your setup?

I use emacs-jupyter, which has async execution. Sorry for the late reply, only just now noticed this!

There is ob-async that worked well back when I tried it. Might be worth a look if the synchronous nature of the executions is slowing you down.
