LagSlayer plugin

  • TPS-aware sweeps trim aged items, projectiles, idle vehicles, and invalid entities within a fixed budget so cleanup never causes hitches. Low TPS engages tighter age limits automatically.
  • Chunk spawn guard blocks new natural/patrol/raid mobs in overcrowded chunks, preventing runaway mob piles before they tank performance.
  • Item burst suppression aggressively merges nearby drops on spawn to keep entity counts small without deleting loot.
  • Command /lagslayer status|sweep|reload for live stats, manual sweeps, and reloading config.yml. Defaults target Paper/Purpur/Spigot 1.21.10 and Java 21.

Configuration highlights

  • sweep-interval-ticks, max-removals-per-sweep, and manual-sweep-budget tune how often and how deep sweeps run.
  • emergency-tps lowers age limits when TPS dips; keep respect-named-entities true to protect named/tamed mobs.
  • cleanup.items/projectiles/vehicles control age thresholds and item merge radius/budget.
  • spawn-guard.chunk-entity-cap and guarded-spawn-reasons set per-chunk mob pressure limits.

Notes and limitations

  • The guard only applies to configured spawn reasons; custom/plugin-driven spawns stay untouched unless added.
  • Sweeps honor budgets to avoid stutter, so extreme backlogs may need multiple runs or a higher manual budget.
