It's bizzare to want to run Docker on a Mac anyway. Docker has never and will never run on a Mac natively. The way it works on Intel-based Macs is through the xhyve/hyperkit hypervisor, i.e. it virtualises Linux. That's the only way it can work. It's also why you can limit how many CPU cores and RAM Docker can use, since you're just giving the underlying virtual machine those limits through the Docker settings app. And it's just a memory hog. It will eat RAM up to the amount you specify rather than dynamically allocating and deallocating as per the requirements of each running container like on Linux.
It shocks me that so many people want to run Docker on a platform it was never built for. The suggestion above is not bizzare, it's a normal use case: run Docker on Linux like it's meant to be run.
Docker for Mac has had performance issues for years, especially related to file I/O. The common suggestion is to use NFS to get around those, which is just ridiculous when you think about it. [0]
