Version 5.5 is 2.5 times faster than 6.0 and 7.0

[nipmarsh]

Hi,

I experience slowness when upgrading from 5.5 to 6.0 or 7.0.
5.5 is 2.5 faster than those versions
I'm using python 3.9, django 3.1.5 and restframework 3.12.2

This is related to pyuca install, if not install the speed is good

Could it be related to the pyuca version? Otherwise if you have time, run a bisect and find when the problem started to help narrow it down :)

    class Meta:
        ordering = ['id']

    def __str__(self):
        return '%s' % self.country
