In the interest of preventing further problems before they get serious, I'd like minerduck to take a look at his place. It's currently dropping my FPS severly just looking at it, and being in it is worse. There is a portal from a portal gun in there which I think can be a problem, also a crystal chest which I've read can be problematic. So maybe look into doing something about that. And possibly turn off some machines. I don't know how rotary macerators and such that has to be on all the time affects the server.
I would start with the portal, I have a feeling it is to blame and I would even suggest removing portal guns from the server entirely unless people are very much against that.
