Author here, the article is a very detailed journey about the docker internals till the current actions you can take to improve the performance. You’ll find custom made diagrams (Excalidraw), live terminals (Asciinema) and some gif repo made to run the tests. Let me know if you like it.

I used a Mac at my last job (normally I like Linux) and found Docker performance dismal. This looks like there has been some improvements - thanks for the write up!

Linux remains unbeatable, as always :) thanks
