For the comparison to os x docker, the biggest slowdown for os x docker is the file system mapping. It basically breaks any reasonable performance chart: look up posts getting into alternatives like mutagen. The slowdown makes using an IO-heavy dev flow like live editing via `npm run watch` relatively unusable: 30X+ slowdowns are normal. There might be high CPU overheads too (I recall we had to tweak seccomp), but when basic IO is so slow, the rest doesn't matter.

In contrast, yes, wsl2 has 5% CPU hits (hyperv, ...),but a sane FS mapping, so the total overhead is imperceptible for a windows dev box.

I was pleasantly surprised to see wsl2 Just Work. Our only issue preventing wsl2 from being the official team rec over native Linux has been wsl2's lack of opencl, and that's just specific to our use of GPUs. As someone whose preferred dev box has been osx for ~20 years, even when at MS, I was biased against Windows for most dev... but no longer.
