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: "Data updates" https://www.techempower.com/benchmarks/#section=data-r18&hw=ph&test=update 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: https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/Python/django Imre Colin 't Hart <colinth...@gmail.com> ezt írta (időpont: 2019. szept. 29., V, 23:42): > Hi, > > Can someone take a look at this blog post? > https://www.peterbe.com/plog/redis-vs-postgres-blob-of-json > > Can Redis really be 16 times faster than Postgres?
