So basically, the M1 Macbook Air is two to three times faster than the SQ2, including comparing ARM Windows on the SQ2 against ARM Windows in a VM on the M1 Air.
Relatedly, I wrote this on Twitter a few weeks ago:
cargo build of sccache on a Lenovo Yoga C630 (Snapdragon 850) in WSL: 4 minutes 55 seconds. On a Macbook Air M1: 55 seconds
WSL 1 or 2? WSL 1 has very slow disk access, so compiling can be pretty slow. I.e. I would expect WSL to be slower for disk reasons even it was running on an M1.
