Repeatedly learned lesson: keep FS metadata as close to where you need the data as possible. Sharing or remoting metadata kept a last resort for when it's actually needed by the use case, as doing so always costs orders of magnitude in performance at scale.

If I understand you correctly, then yes, I have eventually decided that I should only compromise on performance where it hurts less, e.g. for IDE access. If you’re running your application on a web server inside the VM for example, then this is the place where you probably need the best performance possible since this is where you’re going to feel it the most.
