- Update benchmarks/v0.4.0/REPORT.md with optimization results: Task A access-log sampling (-29% latency, -65% allocs), Task B file-cache fix (-99.8% allocs, +73% throughput), Task C RemoteAddr string caching. - Add scripts/bench-compare.sh to compare two benchmark summaries and flag regressions beyond configurable thresholds. - Add benchmark-pprof.yaml for reproducible pprof collection.
Key findings from CPU/allocs/heap profiling: - LogAccess consumes 16.36% cumulative CPU (top app-layer hotspot) - os.statNolog dominates 74.95% of allocations (static file path checks) - net.IP.String + net.JoinHostPort account for 9.34% allocations - bufio.NewReader/Writer hold 54.6% of heap memory Includes detailed optimization priorities and next steps.
- Collect baseline benchmark summary across all core modules - Save key results to benchmarks/v0.4.0/summary.txt - Update .gitignore to track benchmark summaries/reports - Include performance optimization design docs and plan
