imho: the "Django ORM" is not so fast.
according to "TechEmpower Web Framework Benchmarks" ...
it has only ~3% performance - compare to the best rust+pg (100%) results.
example:
the "django-postgresql" performance = 766 - only 3.0% of the best pg + rust results
checking the other test types ( "Single query" ;" Multiple queries" ) has a similar results.
the Django implementation of the test:

Hi,Can someone take a look at this blog post?Can Redis really be 16 times faster than Postgres? Surely Postgres can get closer to the raw speed of the hardware than 1 order of magnitude?Thanks,Colin
