/lagtest start 1-2000000 
causes lag

/lagtest status
tells you if there is lag and how much

/lagtest stop
stops the lag

The mod can be used for testing server latency it is not recomended to use more than 2000 because it might make it unplayable. this mod does not decrease your fps it can cause your fps to go up but that's just an unintended effect of the chunks loading slower.

Mod compatibility is untested so it could possibly break other mods so be advised while using this mod with any other mods.
