![Adaptive Performance Tweaks: Spawn][header]

Server-side Forge module that optimizes mob spawning: smarter distribution, spawn limits, and spawner tweaks to keep entity counts under control. Works standalone on the server; clients are optional.

Status ✅

Stable 11.x Classic / LTS module for existing Forge modpacks.

Critical fixes and compatibility updates may be provided when needed. New features, new loader support, and modern Minecraft version updates are developed in the new all-in-one Adaptive Performance Tweaks version.

Requirements 🧩

Requires [Adaptive Performance Tweaks: Core][core_mod]

Features ✨

• Server-side only; clients do not need to install the mod.
• Pick only the modules you want; highly configurable via config files.
• No core/mixin patches → broad mod compatibility.
• Built-in debug info to see what the optimizer is doing.

⚠️ Always keep regular backups of your world.

Spawn optimizations 👾

• Optimized mob spawn calculations around the player for better distribution and fewer entities.
• Basic spawn control: per-player/world caps, allow/deny lists, and presets for popular mods.
• Adaptive spawn rate considers players, caps, server load, and game difficulty.
• Spawner optimization: track loaded spawners and apply lightweight tweaks.
• Configurable via adaptive_performance_tweaks/spawn/*.toml.
