Mob Limits

Limits on Large Groups of Mobs.

To optimize server performance, large clusters of mobs are regulated.
Entities are not limited per chunk but are limited by their group (see below).
Groups of mobs that exceed the limit are periodically identified and culled,
exempting those with special characteristics like being a custom mob or tamed.
When a mob is removed, you will see a smoke effect.

For example, if the limit is 10 mobs within 5 blocks, it will group all mobs in the same group
that are less than 5 blocks from each-other into one large group and remove the excess mobs.

If you wanted to have more than 10 mobs in this example, you need to have at least 5 blocks
between your groups to prevent them being counted as one group.
