ChadScript compiles through LLVM, the same backend behind C and Rust — so it gets the same optimization passes. Compared against C, Go, and Node.js on Apple Silicon. **Median of N=10 runs**; full 95% bootstrap confidence intervals on the [benchmarks dashboard](https://cs01.github.io/ChadScript/benchmarks).

| Benchmark | ChadScript | Node.js | vs Node | C |
| --------------- | ---------- | ------- | -------- | ------ |
| SQLite | **0.079s** | 0.165s | **2.1x** | 0.080s |
| JSON Parse | **0.002s** | 0.004s | **2.0x** | 0.002s |
| Monte Carlo Pi | **0.264s** | 2.486s | **9.4x** | 0.265s |
| Matrix Multiply | **0.109s** | 0.137s | **1.3x** | 0.099s |
| Fibonacci | **0.516s** | 1.502s | **2.9x** | 0.442s |
| Sieve | **0.012s** | 0.025s | **2.1x** | 0.008s |
| Quicksort | **0.140s** | 0.159s | **1.1x** | 0.121s |
| N-Body Sim | **0.824s** | 1.089s | **1.3x** | 0.774s |
| File I/O | **0.054s** | 0.072s | **1.3x** | 0.027s |
| Binary Trees | **0.604s** | 0.368s | 0.6x | 0.854s |
| Cold Start | **5.9ms** | 27.4ms | **4.6x** | 6.8ms |

**Statistically tied with C on 3 benchmarks** (SQLite, JSON, Monte Carlo — 95% CIs overlap). **Beats both C and Go on Binary Trees** — but loses to Node's V8 JIT which eliminates allocations via escape analysis. **Matches Go within 5% on Matrix Multiply, N-Body, Monte Carlo, and Sieve.**

**🥇 on 4 benchmarks** (SQLite, JSON, String Manipulation, Cold Start — all statsig tied with or beating C via 95% CI overlap). **Beats Node on every benchmark except Binary Trees**, where V8's JIT eliminates allocations via escape analysis. **Matches Go within 5% on Matrix Multiply, N-Body, Monte Carlo, and Sieve.**
