ChunkEntityLimiter

Entity and Item Chunk Limit Cleanup Plugin for Folia, Paper, Bukkit, Purpur, Spigot.

This optimization method enhances Minecraft server performance by intelligently limiting entity and item drop counts in both individual chunks and player-surrounding chunks.

You can modify the default configuration in the ChunkEntityLimiter folder under the plugins folder.

Provide the following 4 commands:

config.yml

# Entity and item drop limits configuration. It will only clear parts that exceed the limits.
entity-limits:
  # Default maximum number of entities allowed per chunk (all entities except those with special configurations)
  default-limit: 100
  # Maximum number of item entities allowed (item drops), note that this counts the merged stack of items
  item-limit: 300
  # Check interval (in game ticks, 20 ticks = 1 second)
  check-interval-ticks: 200  # This means the check occurs every 10 seconds
  # Whether to check chunks around the player. 0 means disabled.
  # Example: If chunk-check-radius: 1 and default-limit: 100, the total limit for all chunks (3x3) within radius 1 around the player is also 100. Single-chunk limits still apply.
  chunk-check-radius: 1
  # Multiplier for entity limits in chunks around the player.
  # Example: If chunk_entity_multiplier: 1.5, chunk-check-radius: 1, and default-limit: 100, the entity limit for all chunks (3x3) within radius 1 becomes 100 * 1.5.
  chunk_entity_multiplier: 1.5
  # Multiplier for item entity limits in chunks around the player.
  # Example: If chunk_item_multiplier: 1.5, chunk-check-radius: 1, and default-limit: 100, the item limit for all chunks (3x3) within radius 1 becomes 100 * 1.5.
  chunk_item_multiplier: 1.5
  # Ignored entity types (these will not be counted or cleared)
  ignored-types:
    - IRON_GOLEM
  # Ignored item types (these will not be counted or cleared)
  ignored-items:
    - DIAMOND
    - NETHERITE_INGOT
    - ENCHANTED_GOLDEN_APPLE
