Looks cool but wtf are you building?
kinda hard to picture what its spos to be lol

Wonder if there is a way to reduce the amount of chucks loaded around the player in the nether, would probably help quite a bit.

Should probably ban the nether roof at this point causes tons of lag, There is a nether highway so its not really needed to get far out.

Also a pretty serious bug which causes lag with nether portals and entities, not sure how much it could be effecting this server.
