APTweaks: Items (11.x Classic)

by Kaworru

APTweaks: Items is a server-side Forge and NeoForge module that clusters dropped items and experience orbs and removes garbage entities to keep server tick rate steady.

ForgeNeoForgeServer-side onlyMIT LicenseOpen source1.18.2 – 1.21.1

What it does

Dropped items that fall close together merge into a single entity, which lowers the entity count after large farms, mining sessions or big TNT explosions. Experience orbs in range are clustered and their values are combined. The module also cleans up excess or oldest items on a timer and adjusts item lifespan to the current server load.

Modules can be enabled one at a time through config files, and the mod includes built-in debug output that shows what the optimizer is doing. It applies no core or mixin patches. The mod requires APTweaks: Core (11.x Classic), and APTweaks: Gamerules, APTweaks: Player and APTweaks: Spawn (11.x Classic) are optional. The mod is published for Forge and NeoForge across 14 release versions, 1.18.2 – 1.21.1, and is released under the MIT License as open source.

Key features

  1. Dropped item merging

    Items dropped within a small radius are combined into fewer entities, reducing the load on the server.

  2. Experience orb clustering

    Nearby experience orbs are grouped and their values summed, so the server tracks fewer orb entities.

  3. Garbage cleanup

    Excess and oldest items are removed periodically, and the lifespan of remaining items shortens or lengthens with server load.

  4. Modular configuration

    Each optimization module can be switched on or off, and the thresholds are set in config files.

  5. Debug output

    Built-in debug information reports what the optimizer is merging, clustering and removing.

Use cases

Large farms

Mob and item farms produce many drops at once, and merging keeps the entity count manageable.

Mining sessions

Long mining runs leave many dropped blocks and orbs behind, which the cleanup and clustering reduce.

Who it’s for: Server owners running existing Forge or NeoForge modpacks who want item and orb lag reduced without installing anything on player clients.
