Mods

The intelligent performance modulator for Minecraft Server. LagShield Ultimate uses Arclight-safe async processing to dynamically regulate mob AI, chunk density, and entity speed based on real-time server stress (MSPT). Stops lag before it happens.

Description

LagShield

Server-side performance mod for NeoForge 1.21. Monitors server load in real time and dynamically adjusts entity AI, mob spawns, and movement speeds to keep TPS stable. No client install required.

Features

Adaptive system — reacts to live MSPT, no static limits
Async mob AI and density calculations off the main thread
Per-chunk mob limits that scale with server load
Tick rate controller — distant entities think less often
Per-mob config (mob_spawns.json) — auto-generated, edit spawn weight and mob cap per entity
Bosses, villagers, tamed animals, and name-tagged mobs are always protected
/lagshield reload — reload all configs without restarting

Configuration

Config lives in config/lagshield/ — lag_features.toml for module settings and mob_spawns.json for per-mob spawn control.

Compatibility

Designed for hybrid servers (Arclight, Mohist). Originally developed for the Werewolves vs Vampires modpack.
