Lagging? Curious if the lag is on your end or ours? Simply type the LAG command!
Processing lag refers to delays in executing code, and may occur if the game is doing a lot of processing intensive things at the same time. Usually, however, this is originating from some other process on the server but outside of the game.
Network lag refers to delays in sending input and output over the internet, and is essentially a measurement of the server's connection to its internet service provider.
There is no form of gamewide lag which will not appear as either processing or network lag. Asking other players or the staff whether the game is lagging is never necessary. The LAG command will always provide the definitive answer, without exception!
