I've recently made a mob farm that uses basic knowledge of Minecraft to make. It doesn't contain any spawners of any type so it can summon any type of mobs from the overworld excluding Enderman. Mob spawn rates has been... disappointing. As a result, I've started to wonder if any of you have mob farms without using mob spawners and how much mob spawns in a minute in that farm? Post the results down below and if have an efficient mob farm, take a screenshot and post it here.
