If you're getting a very low framerate, then it's not called lag, it's called FPS drop or frameskipping.
Lag is slow communication between the server and client, which results in not being able to interact with the game temporarily. The server has been giving 5-10 second lag spikes since the new world (probably longer but I wasn't playing much).
Come back two hours earlier.
