The issue you're running into is that to run docker on mac, you have to run it in a vm. Docker is fundamentally a linux technology, so first emulate x86_64 linux, then run the container. That's going to be slow.

There are native macos containers, but they arent very popular

Docker can run ARM64 linux kernel, no need to emulate x86

You still pay the VM penalty, though it's a lot less bad than it used to be. And the Arm MacBooks are fast enough that IME they generally compare well against Intel Linux laptops even then now. But it sounds like first-class GPU access (not too surprisingly) isn't there yet.
