Legend & methodology

Indicators: 🟢 > 1% faster | 🔴 > 1% slower | ⚪ within noise margin

vs webpack: compares @lazarv/rsc against react-server-dom-webpack within the same run.
vs baseline: compares @lazarv/rsc against the previous main branch run.

Values shown are operations/second (higher is better). Each scenario runs for at least 100 iterations with warmup.

Benchmarks run on GitHub Actions runners (shared infrastructure) — expect ~5% variance between runs. Consistent directional changes across multiple scenarios are more meaningful than any single number.
