So /warp pvpold is located above the prison cells. and in these cells you got auto enchanter/auto potion brewers/herbalism grinders. which all of them have redstone. and there are alot of item frames (item frames = entities. ss 1 I am at warp freeworld and I am getting 102 fps. ss2 I am getting 57 fps at warp pvpold. ss 3 I am getting 3fps at warp pvpold looking down "where the cells are" so I hope that we can fix this problem by moving warp pvpold to a different location to fix this issue.
