OptimizationUtils

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

Features

• Automatic Mobcap - Automatically prevents mob spawning when server performance drops below configured thresholds (based on MSPT) (see config).
• Dynamically set simulation distance - Automatically sets simulation distance for all worlds with proper despawn range adjustments following Paper optimization guidelines
• Advanced Mob Spawn Control - Configure mob spawn limits and spawn frequency for different categories (MONSTER, ANIMAL, etc.)
• Chunk Entity Analysis - Analyze loaded chunks to identify areas with the highest entity concentrations (shows top 10 chunks)
• Animal Out of Range Cleanup - Remove animals that are outside specified range from players to reduce server load

Commands

Base command: /optimizationutils (aliases: /ou, /opt)

• /ou reload - Reloads the plugin configuration.
• /ou info - Displays server and plugin information.
• /ou setsimulationdistance <distance> - Set simulation distance for all worlds. This also changes spigot and paper configs according to https://paper-chan.moe/paper-optimization/?ref=paper-chan.moe#despawn-ranges-notes
• /ou setviewdistance <distance> [player] - Set view distance for all worlds or for a specific player.
• /ou setspawnlimit <category> <limit> - Set mob spawn limit (MONSTER, ANIMAL, etc.). Equivalent to spawn-limits in bukkit.yml. (ref)
• /ou setticksperspawn <category> <ticks> - Set mob spawn frequency. Equivalent to ticks-per in bukkit.yml. (ref)
• /ou analyzechunks - Shows in which chunk are the most entities.
• /ou killoutofrange <entity type> <range> - Kills specified entities that are out of the given range from the player. This is useful for servers with a lot of entities, as it can help reduce lag.

All these commands only set the values in memory, they do not change the config files. The changes will be lost on server restart.
