I was fixing up a Django app https://github.com/mark0978/django-softdelete and setting up tox to make sure it worked with all the listed versions because of issues opened on the original repo. While I was running tox locally I noticed that with every version of Django, the tests ran slower, and from 1.8 -> 2.2 the test time was nearly doubled. This was true for every version of python tested from 2.7 - 3.7.
If you want to check this on your machine, just grab the repo and run tox. I'm including the minimal tox output to show this phenomenon. py27-A installed: DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020.
