How is near native performance achieved

[gitcomit8]

As I can see the docker spins up another vm of arch Linux that runs the osx-kvm. I tried to do this same but did not achieve the same performance.

"Run Mac OS X in Docker with near-native performance!"¹.
What does it mean? Is it some minor performance penalty or not compared to running on Linux using QEMU with KVM? What are benefits running on Docker?

Graphics penalty but compute can be higher than a real mac by passing through all CPU threads.

@sickcodes, impossible magic! How it possible to have more threads than real hardware? 🤣 I need some real true facts (measured values etc.) to believe this nonsense. Can you provide?
