Efficient pickling for django models.
Makes django models pickling 2-3 times faster and compact.
$ pip install django-pickling
Then add django_pickling to your INSTALLED_APPS.
In both cases you should wipe your cache or change keys. Note that you will need to deal with this anyway, with django-pickling you’ll just get weirder errors.
Another thing is that objects with deferred fields are not optimized.
