> on MacOS you're running a Linux VM and have overheads of moving data between that and your main OS MacOS is a special beast, because if I run a VM myself inside parallels using Docker (Ubuntu server with the docker snap, for example), I get nearly 5x the performance from that VM than I do just the "regular" docker for mac (including when all of the new mac specific experimental options are enabled for better performance). It's pretty atrocious, I find it completely unusable and just stick to running my containers in Parallels and forwarding the ports.
