Fast Chunks

FastChunks — Adaptive Chunk Loading Acceleration Plugin

FastChunks is a modern chunk-optimization plugin for Paper/Bukkit/Spigot/Purpur servers that want faster, smoother world loading for
players without unsafe server strain.
It adds adaptive + directional prefetching, priority-based chunk scheduling, fairness controls, and backpressure-safe limits, all
configurable in config.yml.

Built for player experience, server stability, and real-world multiplayer traffic.

✨ Adaptive Loading Engine

Dynamic prefetch radius scaling based on TPS + player speed
Directional prefetch cone to load chunks ahead of player movement
Smart radius up/down behavior for stable vs stressed server conditions
World-specific overrides for different terrain/loading policies

🚀 Priority-Based Chunk Scheduling

Event-aware priority queue (Teleport, Join, World Change, Movement, Warmup)
Distance-aware prioritization inside each prefetch batch
Important player transitions processed before low-priority background tasks

🛡️ Stability & Fairness by Design

Per-player queued/in-flight limits to prevent single-player domination
Queue backpressure controls to avoid overload under high traffic
Dedupe TTL protection to prevent repeated chunk request spam
Safe fallback behavior across different server software implementations

🌍 Hotspot Warmup Toolkit

Configurable warmup hotspots (spawn, warps, hubs, event zones)
Interval-based preload cycles to keep popular areas responsive
Supports chunk-coordinate targeting for precise warmup coverage

📊 Admin Visibility & Live Tuning

/fastchunks status for active config and runtime budget visibility
/fastchunks stats for queue/in-flight/completion/skip metrics
/fastchunks profile <safe|balanced|aggressive> for one-command tuning
/fastchunks reload for config refresh without restart

⚙️ Fully Configurable in config.yml

Adaptive radius thresholds and bounds
Directional cone and forward boost behavior
Queue budgets, per-player fairness limits, and dedupe TTL
Hotspot warmup definitions and world override policies
