Looking at the Django's [https://django.github.io/django-asv/ ASV
benchmarks ] the [https://django.github.io/django-
asv/#query_benchmarks.query_count.benchmark.QueryCount.time_query_count
query count ] and [https://django.github.io/django-
asv/#query_benchmarks.query_aggregate.benchmark.QueryAggr.time_aggregate
aggregate ] benchmarks show performance regressions.
Rough orders of magnitude are
Query Count 1.257ms -> 1.849ms 47% Increase
Aggregate 0.882ms -> 1.238ms 40% Increase
I managed to bisect the regression to this commit
