Usage

Run your python program with the -X importtime option, available since Python 3.7.

The program will output timing statistics on stderr :

import time: self [us] | cumulative | imported package
import time:       137 |        137 | zipimport
import time:       674 |        674 | _frozen_importlib_external
import time:        84 |         84 |     _codecs
import time:       705 |        789 |   codecs
import time:       757 |        757 |   encodings.aliases
import time:      1115 |       2659 | encodings
import time:       461 |        461 | encodings.utf_8
import time:       190 |        190 | _signal
import time:       488 |        488 | encodings.latin_1
import time:        72 |         72 |     _abc
import time:       456 |        528 |   abc
import time:       574 |       1101 | io
import time:       102 |        102 |   _locale
import time:       319 |        420 | _bootlocale

Copy these stats and then paste them using the button in the web page above.

You can also save the stats to a file and open the file in the web page.
