I stood up a brand new fresh Rust server and noticed that my plugins were robbing the server of several FPS. After unloading them all and re-adding them one-by-one, I discovered that Zone Manager was the culprit. When I load the plugin, server.fps drops by about 7 and proceeds to fluctuate in the 5-7 fps drop range. When I unload it, the server consistently runs at the original number at about 7 fps. There are no other players, structures, plugins, or events on this server when performing this test, as I wanted to remove all the variables. Any efforts to make this wonderful plugin less resource intensive would be immensely appreciated.

Yeah i am noticing this also on my server. Zone Manager sucking memory like crazy 
You can see below it is above everything and then the moment I restart it boom server goes back to good. It just keeps sucking with no reset or recovery.

I just set a timed command to reload the mod every 2 hours. 

While that may help with whatever memory leaks are there, it doesn't explain the high CPU (server.fps hit) that I'm also seeing. I'm assuming there is either a tight loop somewhere in this code, or an over abundance of hook calls.
