In order to optimize the server performance, several changes have been made which could alter the way mob farms work. The most notable changes are as follows:

  • The hostile mob cap is per-player rather than per-world.

  • The entity cramming limit is set to 8.

  • The soft despawn range is 28 and the hard despawn range is 96.

  • The ticking view distance is 4.

  • If many iron golems already exist near a village, the village will not spawn any new iron golems.

  • Villagers tick significantly less often when the tps is low.

  • Villagers will run their acquirepoi behavior 1/4 as often.

  • Zombies are not aggressive towards villagers when the tps is low.

  • A chunk will only save up to 1 hopper minecart and 16 of any individual passive mob type. Any extras will despawn when the chunk is unloaded.

  • Entities that are far from players tick less often.

  • Piglin runs on Purpur which includes all of Paper's patches, some of which might slightly toy around with technical details, but aims to be as close to vanilla as possible.
