⚡ UltraPerformance — The Ultimate Server-Side Optimization Suite
UltraPerformance is a lightweight, all-in-one performance enhancement and security plugin designed specifically for high-traffic PaperMC and Purpur servers (1.21.1+).
Instead of cluttering your server with dozens of unoptimized plugins, UltraPerformance unifies cutting-edge algorithmic improvements inspired by the most famous Fabric optimization mods, adapting them seamlessly into safe Server-Side logic.
🚀 Core Optimization Modules
🔹 Chunk & Lighting Engine (Lithium & Starlight Inspired)
- Asynchronous Lighting: Offloads heavy block and chunk lighting updates to background threads, preventing main-thread stuttering.
- Cascade Suppression: Dynamically blocks redundant block-change cascades, saving precious CPU cycles during heavy world interactions.
🔹 Intelligent Entity Culling (Entity Culling & Dynamic FPS Inspired)
- AI Throttling: Smartly freezes pathfinding and collision checks for mobs inside chunks with no active players.
- Whitelist System: Fully customizable whitelist (Players, Villagers, Armor Stands) to guarantee your server mechanics and farms never break.
🔹 Memory & Asset Management (FerriteCore & Memory Leak Fix Inspired)
- Garbage Collection Hints: Automatically triggers lightweight memory sweeps during low-player activity to keep RAM usage stable.
- Metadata Purging: Forces clean-ups of orphaned tile-entity and chunk section metadata upon unloading, completely stopping long-term memory leaks.
🔹 Smooth Loading & Network Packet Optimizer (LazyDFU & FastLoad Inspired)
- Asynchronous Login Preload: Caches chunks around player login or teleport coordinates before spawning them, wiping out "Join Lag Spikes."
- Packet Batching: Compresses and batches massive entity metadata packets sent to distant clients, optimizing the network thread.
🛡️ 24/7 Security & Watchdog Guard
- Intelligent Anti-Bot Protection: Intercepts sudden network connection spikes at the pre-login stage using lightweight packet challenges. Drops malicious bot attacks before they can load player data or impact the main thread.
- Anti-Lag Crash Guard (TPS Watchdog): Constantly monitors TPS and MSPT. If the server enters emergency status (TPS < 12), it automatically toggles configurable safety measures (pausing chunk generation, freezing item physics, reducing view distance) until the server recovers.
⚙️ Fully Customizable Configuration
Every single feature, threshold, radius, and module can be toggled and tweaked via the config.yml file to fit your server's exact hardware capabilities and player base needs.
🛠️ Supported Platforms
- PaperMC (1.21.1 and higher)
- Purpur (1.21.1 and higher) — Fully compatible with native Purpur performance methods.
