### Allocation (GC)
| Operation | `Buffer.allocUnsafe` | `Buffer.allocUnsafeSlow` | `PoolAllocator` | Speedup |
| ---------------- | -------------------: | -----------------------: | --------------: | ------: |
| alloc 64 bytes | 400.46 ns | 167.94 ns | **6.33 ns** | 63.3x |
| alloc 256 bytes | 309.57 ns | 500.58 ns | **6.35 ns** | 48.7x |
| alloc 4096 bytes | 653.40 ns | 620.19 ns | **6.32 ns** | 103.4x |
Under GC pressure, the advantage grows dramatically — up to **103x** faster — because `PoolAllocator` reuses slots from a pre-allocated buffer and never creates objects for V8 to trace.
### Slice creation vs `Buffer.subarray`
