Exactly the same observation on Linux. E.g. #1 the slowest, #3 quite
good, #2 perfect. However:

with #2, if I did copy and paste of some command into the python
terminal, I could see how ipython was putting the command letter by
letter on the prompt, e.g. by pasting "inputhook.remove_inputhook()" I
could literally see:

i
in
inp
inpu
...

(everything on one line, e.g. like if there was sleep(0.05) between each letter)

with #1 and #3, pasting was immediate.
