Improve volume performance on macos

[jonathan-boudreau-work]

Feature request description

Volumes are pretty slow on macos, significantly slower compared to the performance I can get on docker.

Suggest potential solution

Caching on the VM side is something docker for mac seems to do.

Have you considered any alternatives?

Libkrun doesnt seem to work for me, other than that not sure what else I could try.

Additional context

I'm trying to do development on a monorepo, with a volume pointed at it. Things such as git status take over 2 seconds.

[jakecorrenti]

What about Libkrun isn't working for you?

[jonathan-boudreau-work]

It fails to download krunkit due to bad CPU type in executable.

[jakecorrenti]

It looks like you're on an Intel Mac. Libkrun only supports Apple Silicon CPUs
