# App-pattern bench matrix — 2026-05-21 23:02:43

Each cell is mean ms (min ms). Lower is better.
Final column is **perry/bun ratio** — > 2× is a real gap, < 1.5× is fine.

| Kernel | Perry | Bun | Node | perry/bun | perry/node |
|---|---:|---:|---:|---:|---:|
| object_deep_clone | 51.8 (41.2) | 41.0 (24.5) | 100.2 (87.4) | 1.26x ✓ ok | 0.52x |

## Summary

- Perry-faster-than-Bun kernels: **0**
- Borderline (1.5–2× slower): **0**
- Slow (≥ 2× slower): **0**

**Priority backlog:** the ✗ slow rows are the gaps. Each one is a focused workstream.
