No Mob Generation
No Mob Generation is a Fabric server mod that stops animals from spawning in newly loaded chunks, which can otherwise cause lag.
What it does
Animals normally spawn into chunks as they load, and when the mob cap is already full, new animals still appear. This mod keeps animals from populating chunks, so players do not spend time searching for animals that spawned because the cap was already reached. Experience orbs are also reduced in new chunks. Its author states that it helps prevent lag. The mod is server-side only, so players join without installing it. Its one version, 1.0.0, was published on 2022-01-29 for 1.18.1 and is released under the GNU General Public License v2.0 only, as open source.

Spawns even at a full mob cap
Animals no longer appear in newly loaded chunks when the mob cap is already filled.
Fewer experience orbs
Experience orbs are reduced in newly loaded chunks, which the author says reduces lag.

What the author says
When loading new chunks new animals will spawn even if your mob cap is already full. This mod prevents that so you will experience less lag in new chunks.
