Expand benchmark to three runtimes - #8
Merged
Conversation
📝 WalkthroughWalkthroughThe benchmark now measures managed, Rust/.NET, and native Rust runtimes. It validates matching content hashes, records runtime-specific metrics, handles unavailable allocation data, and updates localized benchmark documentation. ChangesThree-runtime benchmark comparison
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change adds native Rust benchmark reporting, but the result check can miss row-structure differences and the published instructions and methodology do not consistently describe the new three-runtime harness. Resolve these issues before merging so benchmark correctness and reproducibility claims remain reliable. Sequence Diagram(s)sequenceDiagram

three-runtime benchmark by either adding its environment metadata or explicitly
labeling the later August 28, 2026 environment block as legacy. Apply the same
clarification to docs/dotnet-v1-query-benchmark.md lines 35-37 and

docs/dotnet-v1-query-benchmark.md (lines 23-26) and
docs/dotnet-v1-query-benchmark.zh-CN.md (lines 23-26) must align with the
three-path NuGet harness: update Scope and Fairness Controls to consistently
describe MiniExcel.Query, MiniExcelRust.Query, and native MiniExcel::query
instead of two runners and “both,” or explicitly limit the methodology to the
legacy two-runtime report.
In `@miniexcel/examples/stress_query.rs`:
- Around line 83-86: Update the row hashing loop around append_text so
content_hash encodes row boundaries unambiguously, such as by adding a canonical
row marker or per-row cell count before each row’s cells. Apply the identical
canonical format in the managed hash implementation so all three runtimes
produce matching hashes while distinguishing different row structures.
In `@scripts/compare-nuget-v1-rust.ps1`:
- Around line 184-186: Update the preflight flow around Invoke-MeasuredProcess
so all three preflight measurements are retained, then validate their row, cell,
and content-hash dimensions before entering the measured iteration loop.
Preserve the existing validation logic and fail before any measured workload
runs.

Align the methodology scope with the NuGet harness.
In both documents, Scope and Fairness Controls describe two runners and use “both” for validation and measurement controls. The NuGet harness compares three paths: MiniExcel.Query, MiniExcelRust.Query, and native MiniExcel::query. Update the methodology for all three runtimes, or state that it applies only to the legacy two-runtime report.

Encode row boundaries in content_hash.
The hash appends only a flat sequence of cell names and values. Two runners can return the same Rows, Cells, and hash while assigning the same cells to different rows. For example, [A=x, B=y] / [C=z] and [A=x] / [B=y, C=z] produce the same sequence.
Add an unambiguous row record or per-row cell count to the canonical hash format. Update the managed hash implementation to use the same format. This makes the three-runtime validation detect row-structure differences.

Validate preflight output before measured iterations.
Line 184 discards each preflight result. The row, cell, and content-hash check runs only after every measured process completes. A mismatched native runner therefore consumes the full benchmark workload before failure.
Retain the three preflight measurements and validate their dimensions and hashes before entering the measured loop. This also matches the documentation claim that validation occurs before measurement.
