## Summary Benchmark infrastructure for measuring render pipeline performance. - **render-pipeline benchmark** (`bench/render-pipeline/`): `benchmark.ts` for profiling render paths, `analyze-profiles.ts` for CPU profile analysis - **Stress routes** (`bench/basic-app/app/streaming/`): light, medium, heavy, bulk, wide, chunkstorm variants for different streaming load profiles - **Basic app harness**: `benchmark.sh` runner script, `next.config.js` - **Minimal server**: `bench/next-minimal-server/bin/minimal-server.js` - **Docs**: `bench/BENCHMARKING.md` guide - **Config**: eslint exclusion for bench paths, package.json bench scripts ## Test plan - [ ] No runtime behavior changes - [ ] Benchmark scripts are standalone tooling --------- Co-authored-by: Tim Neutkens <[email protected]>
