Docker has much better IO perf with lot of small files on WSL vs Mac. Currently doing Rails development and had to revert to running local straight up on Mac vs Docker because on Docker it was extremely slow. This of course means more testing on prod like cloud envs so it is really a load of crap.

I've experienced this with IO performance for huge files too. A while back I setup a caching service on a spare older Mac Mini first with Docker for macOS and when it couldn't keep up I installed Windows and it was slightly better but still crap. I threw Ubuntu on it and I was saturating the gigabit connection without breaking a sweat.

I'm also a Rails dev and I do all my dev work on an M1 mac and don't even have Docker installed, though I've heard it has improved a lot recently.
