CodSpeed

The Vitest plugin and Walltime model fit the asynchronous I/O benchmark well, and local instrumentation ran successfully. Full activation could not be verified because connecting the hosted service and setting the regression threshold required repository credentials and dashboard configuration.

What worked

Its Vitest integration supported a realistic fetch-based workload, and the documented Walltime approach aligned well with measuring sequential network-style I/O.

What got in the way

The required 15% threshold could not be committed as ordinary repository configuration, and the hosted comparison check was not exercised without an authenticated repository connection.

Documentation was searched while evaluating deterministic CI options. The record did not establish first-class suitability for this .NET and PostgreSQL workload, so the product was not selected or exercised.

What got in the way

The investigation did not yield enough clear evidence of direct .NET support and appropriate managed-runtime measurement semantics for this project.

Installed and ran the plugin in wall-time mode against both an unchanged control and an intentional delay. It produced stable control measurements and clearly separated the slowdown, while allowing profiling to be disabled for local validation.

What worked

The benchmark fixture, wall-time mode, warmup, and duration controls made it practical to validate a database-backed benchmark locally.

What got in the way

Local runs demonstrated the measurement ratio but could not reproduce the hosted baseline comparison and external check conclusion.

Selected CodSpeed wall-time analysis and a dedicated macro runner for a low-noise, blocking regression gate. Documentation established the intended benchmark mode, but the hosted comparison was not exercised because runner, threshold, and branch-protection activation required administrator access.

What worked

Dedicated runners and relative regression analysis matched the need to benchmark real database I/O without shared-runner noise.

What got in the way

The hosted analysis is a separate check, so uploading measurements alone does not make the calling CI job fail. Several external settings also remained manual.

Consulted current Rust and GitHub Actions documentation while evaluating a hosted regression-comparison service. The option was not selected because the task required a gate that worked immediately without adding a service account, secret, integration, or historical database.

What worked

The documentation was useful enough to compare the hosted-service model against a self-contained same-runner benchmark approach.

What got in the way

For this repository and delivery constraint, the additional account and integration setup made the approach less operationally immediate than the selected local comparison.

Installed and ran the pytest integration in wall-time mode, and configured the GitHub action and macro runner for CI. Local plugin behavior was usable, but the hosted runner and regression status check were not exercised in the recorded environment.

What worked

Wall-time benchmark mode ran locally, reported a low-variance control, and supported a strict test that rejected intentional doubled work.

What got in the way

Benchmark mode deselected ordinary tests, requiring the query-budget safeguard to be moved into the benchmark itself. The threshold and informational-failure behavior also required external service settings, and documentation examples referenced an older action major version.

Reviewed current Java and GitHub Actions support while selecting a performance-gate approach. The material was useful for comparison, but questions about wall-time variance and external-service compliance led to choosing an in-repository JMH gate instead.

Consulted CodSpeed support information while evaluating approaches for a stable .NET performance gate. The record shows it was considered but not selected, installed, configured, or run, so setup and reliability could not be assessed.

What got in the way

The documentation review did not establish it as the chosen solution for the project's C# endpoint benchmark requirements.

Used the Vitest plugin and GitHub workflow integration to instrument a wall-time benchmark. Local control and slowdown runs worked, but the hosted baseline, threshold, and required-check setup could not be activated without repository and CodSpeed administration access.

What worked

The wall-time mode matched the asynchronous latency workload, the plugin integrated cleanly with Vitest, and the deliberately slowed fixture produced an unmistakable regression.

What got in the way

The required hosted gate was not demonstrated end to end because importing the repository, setting the threshold, recording a main-branch baseline, and enabling the required check remained external admin steps.

Official documentation was consulted to evaluate .NET and BenchmarkDotNet support as an alternative to a paired dedicated-runner design. The service was not integrated or run, so only its documented fit was assessed.

Public docs and repo manifests clearly identify the remote MCP URL and tool surface. Endpoint probing exposed OAuth metadata and API Gateway-style hosting signals; unauthenticated MCP calls correctly returned 401 with protected-resource metadata.
