What's new
Our Optimizations (PRE_EXISTING_ONLY Mode)
These optimizations assume chunks are always pre-generated (via Chunky or natural gameplay) and DH only needs to process existing chunks, not generate new terrain.
| Optimization | File | Impact |
|---|---|---|
| Force PRE_EXISTING_ONLY mode | WorldGenerationQueue.java | Ensures all optimizations apply, disables world generation |
| Skip heightmap regeneration | BatchGenerationEnvironment.java | 20-40% faster chunk processing (uses MC heightmaps) |
| Skip biomes step | BatchGenerationEnvironment.java | 5-10% faster (pre-existing chunks already have biomes) |
| ThreadLocal hoisting | ChunkWrapper.java | Eliminates thousands of redundant ThreadLocal lookups per chunk |
| Increase task queue size | PriorityTaskPicker.java | Better throughput for task scheduling |
