Fast Chunks

Fast Chunks v1.3.0 - Autonomous Memory Governor & High-Speed Vehicles

🛡️ Autonomous Memory Governor

• Real-time JVM heap headroom evaluation every 5s to prevent OutOfMemoryError and chunk exhaustion.
• Automatic backpressure throttling when heap hits 85% threshold, shielding production servers from Elytra/Boat spam.
• New admin commands:
  • /fc memory - Inspect live heap percentage, governor status, and total loaded chunks.
  • /fc purge - Instantly flush pending queues and trigger JVM garbage collection.

🚤 High-Velocity Vehicle Prefetch Stream

• Tailored lookahead streaming (8 chunks ahead within a focused 40° conic angle) for high-velocity vehicles:
  • Blue ice highway boat transit (60+ m/s)
  • High-speed minecart rail lines
  • Boosted horses
• Prevents players from hitting unloaded chunk barriers at extreme speeds.

⚙️ Concurrent Terrain Generation Throttling

• Segregates async cached chunk loads from new world generation (max-generating-in-flight: 2).
• Eliminates CPU spikes caused by exploratory flight into ungenerated territory while keeping pre-cached loading blazing fast.

🖥️ Interactive GUI v1.3.0

• Live Memory Governor status indicator & total chunk counts in Engine Metrics header.
• Interactive Vehicle Stream Toggle (Slot 21).
• One-click Emergency Cache Purge Button (Slot 25).

🌐 Compatibility & Performance

• Full support for Spigot, Paper, Purpur, and Folia (1.20 - 1.21.4). Tested and verified on Paper 26.3 with Java 25 LTS.
