Additionally I just want to point out this is test done on absolutely default Ubuntu 18.04 with no VM optimizations whatsoever. It's totally possible to significantly improve VMs performance: * By installing / compiling different kernel: low latency preemption option, 1000 HZ timer frequency, etc. * Use HugePages to decrease memory fragmentation. * Play around QEMU own options since right CPU options and host / guest balance with CPU pinning are helpful. I used to improve my CPU-bound games performance on Windows VM a lot by doing some some fine tuning and I suppose macOS not much different.
