OptimizationUtils

A minecraft plugin with some useful optimization utils (see below).

Features

  • Dynamic mobcap - automatically throttles mob spawning (optionally spawners too) when MSPT exceeds a configurable threshold.
  • Dynamic random tick speed - automatically turns random ticks off when MSPT exceeds a configurable threshold.
  • Disable entity ticking - stops ticking selected mobs (they stay in the world, but no AI/movement). Two modes: disabled entity ticking entirely, or uses Bukkit's Mob#setAware. Mobs can be filtered by entity type or Bukkit class, with include/exclude lists.
  • Runtime tweaks via commands - change view distance (globally or per player, persisted), simulation distance, mobcaps, mob spawn frequency and villager tick rates without a restart.
  • Diagnostics - analyze which chunks hold the most entities, kill entities/animals far away from players, and a detailed /ou info overview.
