I wasn't being smug, rather the contrary by assuming you would know |
| 44 |
better than me. |
| 45 |
|
| 46 |
So here we go: |
| 47 |
https://docs.python.org/2/library/profile.html |
| 48 |
|
| 49 |
$ python -m cProfile -o /full/path/to/file.log /usr/bin/command args |
| 50 |
|
| 51 |
This will give you a profile log. |
| 52 |
|
| 53 |
Then you need something to visualize it, I like runsnakerun. |
