SSHFS is about the worst FS in existence. I would only recommend it for a temporary file transfer here and there, but it's nowhere near stable enough to use it like a regular FS.

Oh, I have.

My setup is now Remote VS Code to a Linux NUC that sits on my desk. All code lives on the NUC and all tests run on the NUC, but I can use my MacBook Pro as I move around the house, work outside, etc.

It's pretty seamless, I'm impressed.

I’ve had some success with Mutagen’s [0] Docker support. Essentially you can set up a tiny Alpine container or similar with a volume mounted to it. Mutagen will then keep your code in sync using rsync, allowing you to mount that volume in other containers and bypass the performance hit.

It’s a bit of a pain to set up, and you lose some of the advantages of using Docker in the first place, but if you absolutely have to use it, it can get you back to full performance.

Even without code syncing, running more than 5 or so Docker containers can eat up a lot of RAM and even more CPU. It's just not worth it - put them all in a Linux VM.

I use vagrant boxes (virtualbox) with nfs shares, works well. I'd still do it if I was on linux to be honest. My VMs are provisioned in a way that they have everything installed for the particular project and they are "stateless" in a way that I can and sometimes do reset them to their post-provision state (as virtualbox / vagrant supports snapshots) and my experience with the project stays the same. They are meant to be the perfect environment for a given project and nothing else. The "mutable" stuff is just mounted as nfs shares from my host machine.

The increasing amount of unexplainable hangs and crashes has since offset any of those improvements many times over.

I used it last week...it's still really bad. Running IO heavy tests taking literally 100% more time for me. I'm just running openSUSE MicroOS with podman for my container workloads now, it's been rock solid.
