It is quite literally instantaneous on my 5 year old laptop. Whatever you are seeing isn't due to the choice of Python.

Maybe it's something on my setup then. I notice some delay even though it's by no means huge but noticable. For me these things add up, another example is pane resizing in tmux. I like things snappy, but it's kind of an OCD thing I guess.
