SMPCORE

SMPCORE is a Minecraft server plugin built for one purpose — keeping your SMP running smoothly without the headache of juggling a dozen separate tools. Designed for Paper/Spigot 1.21.10, it handles the stuff that quietly kills server performance before you even notice it's happening. What It Actually Does Keeps your server from choking Entities piling up in chunks, runaway redstone clocks, chunks staying loaded for no reason — SMPCORE deals with all of it automatically. It caps entities at 25 per chunk, stacks nearby ground items together, limits mob spawns in crowded areas, and watches your TPS in real time so it can step in before things get bad. Manages your hardware intelligently If your server is running low on RAM or CPU headroom, SMPCORE notices and adjusts — cleaning up memory, scaling back task frequency, and even triggering an emergency mode when things get tight. Great if you're not running on beefy hardware. Gives you actual access control You get a proper IP whitelist, bot detection with bypass support, and UUID-based player tracking. Whether you're running a tight private server or a bot-heavy automation setup, you can control who (and what) gets through. Little quality-of-life things that matter One-player sleep so nobody has to wait around, configurable join/quit messages, ping tracking, and network-level optimizations that help with packet handling and entity tracking.
