Spawner Limiter

Slows down mob spawner activation rates to reduce the entity-spawn load spawner farms put on a server. Enabled by default. Config file: module/spawner-limiter/config.yml.

spawn-delay-multiplier: 1.5

worlds: []

• spawn-delay-multiplier — multiplies the vanilla spawner delay. 1.5 means spawners take 50% longer between activations than vanilla default; 1.0 is vanilla behavior; values below 1.0 would speed spawners up (not recommended for a lag-prevention plugin, but supported).
• worlds — empty list applies the multiplier server-wide; populate it to restrict the limiter to specific world names, leaving spawners in unlisted worlds at vanilla rates.

This module works alongside — not instead of — Mob Limiter's per-chunk caps; spawner output is still subject to those limits regardless of the delay multiplier here.
