After exploring a lot of the "Suffocation in leaf blocks" issues I have not found this information in comments or issue descriptions. I spent a few hrs exploring a jungle biome I have found that allot of mobs that spawn in jungles die due to suffocation damage. 100's of mob drops sit idle inside of trees or on the ground causing lag.
