## Notes
- This report is a local comparison anchor, not a cross-host release benchmark.
- Memory evidence here is peak working set observed during the benchmark process. Peak handle count is currently only recorded when the runtime can provide it.
- The same-host HTTP comparison now covers a narrow single-connection case (split=1) plus a segmented single-file case (split=4) on the same local loopback server model.
- Each binary/scenario pair now performs one untimed warmup launch followed by repeated timed samples; the side-by-side table reports median elapsed plus fastest..slowest spread so single-run host noise is less likely to dominate the comparison.
- The same-host driver now avoids coarse sleep quantization in its short-process timing and loopback accept path, and it keeps each scenario on one warmed loopback server/port across the timed sample set so Windows first-port cold-path stalls do not dominate the Rust rows.
- Small connector-side wins such as no-proxy reqwest client reuse are still better validated through the direct `ARIA2_RUST_PRO_HTTP_TIMING` breakdown than by whole-process elapsed tables alone.
- The same-host side-by-side table is strongest as a local regression anchor. Some non-Rust reference rows can still pick up host-local cold-path noise, so this report should not be treated as a precision benchmark without corroborating direct runs.
- Shared-runtime multi-download pressure is still represented here through the Rust Criterion anchors rather than the side-by-side table.
- The upstream Windows reference now comes from the official aria2 1.37.0 release artifact downloaded into `<repo-root>\dist\upstream\`.
