Hi, yes, that what I was talking about :-). Now you have a comparison for yourself.

The test provided was not about comparing Docker versus non-Docker but about comparing SQL databases on the same machine, with the same specifications. The goal of the test was to tell you how databases compare between each other with the same settings.
I have four machines at home and surely this test will yield different results for Postgres on each one of them, because one is desktop running Linux, the other one desktop running Windows, the other one is MacbookPro and the last one in Windows laptop. it would not be wise to test Postgres on the worst of them — Windows laptop and compare it with Postgres running on Linux machine, being the powerful one.
That is why the test was made at once on one machine with the same Docker settings.
