because docker. it hard requires a linux kernel and is extremely slow on mac, just like it was on windows until they integrated with wsl.

    I see, I don't use docker all that much on my works Mac. So haven't noticed the speed.

    Also is it the storage share that's slow? As docker desktop is a VM

    well docker on mac is a fully emulated x86 vm. everything is slow.

    It's not that slow. https://www.imore.com/tests-show-apples-m1-emulates-x86-faster-intel-can-run-it-natively

    Edit: actually I just benchmarked it and containerized x86 Linux runs at like 40% of native speed. So yeah, that's pretty freakin slow.

    FWIW arm64 containers ran at nearly native speed, so it's the x86 emulation that seems to be causing the slowdown.

    yeah last i worked with it i was the first person in the company to evaluate the arm macs, and it basically couldn't run our application at all. took a full 40 minutes to spin up, then crashed.
