27774	django admin with many objects count is very slow	Sayid Munawar	nobody	"Django version 1.11a1

i created many (thousands) objects:
{{{
...: count = 500
...: for x in range(0, count):
...:     print(Group.objects.create(name=usr()))
marmut_jahat_4230
hamster_harum_1454
...
kertas_bangga_8357
ular_semangat_5998

In [10]: Group.objects.count()
Out[10]: 4265
}}}

Then go to Admin->Groups, and click one of them. The page will be rendered very slow compared to django 1.10. See screenshots:
