MC-279400 Tick freeze does not pause player effects Duplicate MC-259284 NBT selectors cause severe performance issues with inventories with lots of data Community Consensus

Comments

I have provided the datapack, along with an example of playerdata that causes lag

The main cause of the lag seems to be

@s[nbt={SelectedItem:{id:"minecraft:carrot_on_a_stick",tag:{}}}{{{}{CustomModelData:2}{}}}{{{}}}]

selectors, since the performance increases when reducing the number of them and stays the same otherwise

The datapack will cause a lot more lag when holding a carrot on a stick, because it does an initial check for holding the carrot on a stick and then further checks for the custom model data if they are

No, this issue is server side
