About: Ever noticed that when you randomly teleport players to a location nobody has ever been before that it causes lagg spikes? This is because minecraft still has to generate the terrain and the terrain generator uses up a lot of resources. What PreGenerator does it generates all the terrain in a specified area for you so that when players go explore the map the server doesn't have to generate that terrain.
