I figured swap would only be used if I ran out of available memory. I’m not an expert at all, so I could be totally wrong about that.

Is it possible that the container is allocating the space preemptively but not actively using it? So proxmox would see it as being used, but plex is simply reserving it. I think I’ve seen that occur on other containers like home assistant (but this is a VM not LXC). Proxmox says it’s using almost all the memory available to it, but going into home assistant itself says it’s only using a fraction of that amount.

How is it not suitable for larger homes?

This is a must have for me or I simply don’t use the app. An important detail though: it should only mark posts as read if I’ve scrolled past them! Not any post that can be seen on the screen.
