Yeah, in-game menu, I use it just as a general benchmark of idle speed since the server shouldn't be doing anything while it's up like that constant ~300mb cycle for no reason apparent to me. I'm running an 8 core vishera and the game is allocated 4GB of which it's using ~27%.
Oh, and I noticed chunk loading is stalling somehow unless the server process is put on idle (in-game menu) so it can clear a few thousand e: to f:
