!Adaptive Performance Tweaks: Spawn

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 LTS (Long‑Term Support, Classic Forge). Actively maintained and recommended for new Forge modpacks. After 3+ years of development, this Classic line is highly optimized and battle‑tested. Critical fixes and compatibility updates will be provided when needed. 🛠️

Looking for the next‑gen rewrite for Fabric, Forge, and NeoForge? ➡️ Check out the new Eco Stack Manager.

If your pack runs fine on Classic, no action is required. 👍
