## Benchmark: turbo-persistence — qfilter 0.3.0-alpha.2 vs 0.2.5

**Platform:** arm64 (Apple Silicon)

### Read (1 GiB compacted DB, 85.33Mi entries, 8-byte keys)

| Benchmark | 0.2.5 | 0.3.0-alpha.2 | Change | p-value |
|---|---|---|---|---|
| hit / uncached | 38.05 µs | 39.35 µs | +8.8% | 0.16 (noise) |
| hit / cached | 1.96 µs | 1.92 µs | **-2.3%** | 0.00 |
| miss / uncached | 213.0 ns | 208.4 ns | -1.5% | 0.00 |
| miss / cached | 178.5 ns | 188.0 ns | +3.6% | 0.00 |

### Write (8.33Mi entries)

| Benchmark | 0.2.5 | 0.3.0-alpha.2 | Change | p-value |
|---|---|---|---|---|
| write | 1.132 s | 1.109 s | **-2.0%** | 0.00 |

### Compaction (4Mi entries, 128 commits)

| Benchmark | 0.2.5 | 0.3.0-alpha.2 | Change | p-value |
|---|---|---|---|---|
| incremental | 17.41 ms | 17.94 ms | +3.0% | 0.30 (noise) |
| full | 546.9 ms | 553.9 ms | +1.3% | 0.11 (noise) |

### Summary

The upgrade from 0.2.5 to 0.3.0-alpha.2 is a **neutral-to-slight-improvement** in turbo-persistence benchmarks:
- **Write: -2.0%** — small but statistically significant improvement
- **Read hit/cached: -2.3%** — small improvement
- **Compaction:** no significant change
- No regressions outside noise
