[kwlug-disc] Linux arm64 compilation in vm on m1 silicon?

I'd report that attempt to run x64 linux guest didn't go fast on m1 
host. I wonder if its about qemu settings (adjustable in UTM). I guess 
it can be slow, since there is now direct running on cpu.

If you had same x64-on-m1 situation, what were your observations? How 
does it compare to trivial x64-on-x64 virtualbox on Phenom machine base 
line expectation?


I'd note that our eletron-based app runs faster in m1-package on m1, 
than x64-package on m1. Also lo-o-ong time for electron-build utility is 
now just short on m1. Impression is positive.
