Version: 17.0.1 · MC 1.21.1 · NeoForge 21.1.228 · Java 21

About

Vanilla spawns one XP orb per XP point. Mob grinders kill 100+ mobs/sec → 1000s of orbs entity-tick the server to death. Clumps merges all orbs in a chunk into a single big orb that gives equivalent XP. Massive TPS save for any farming setup.
