## World
|
||
|
||
| Benchmark | Time | Notes |
|
||
|-----------|------|-------|
|
||
| new_default | **1.53 ms** | 3×3 tiles with noise (optimized with rayon: was 10.2ms) |
|
||
| height_operation | 11.4 µs | radius=10, delta=5 |
|
||
| paint_operation | 4.18 µs | radius=10 |
|
||
| serialize_json | 5.25 ms | 3×3 tiles |
|
||
| deserialize_json | 6.37 ms | 3×3 tiles |

||
## Hot-path Summary
|
||
|
||
All benchmarks are **below 10ms**. The only candidate (World::new at 10.2ms) was optimized with parallel tile generation via `rayon` — now **1.5ms (85% faster)**.
