Cedarling Benchmarks#

Cross-platform authorization benchmarks for the Cedarling bindings, regenerated on pushes to main that change jans-cedarling/**, or on a manual workflow_dispatch run against main.

Last updated: 2026-11-02 17:54 UTC (commit 6fd3f26).

Provenance#

  • Each binding is measured on its own GitHub-hosted ubuntu-latest runner. Runners are provisioned fresh per binding, so cross-binding comparisons are unpaired and subject to per-runner variance; read cross-binding ratios as directional rather than exact, especially for closely-matched bindings.
  • Warm-up iterations per scenario: 100; measured (sample count) per scenario: 1000.
  • Exact host, OS, and compiler/runtime versions for this run are recorded in the immutable workflow logs: https://github.com/JanssenProject/jans/actions/runs/41490623514/attempts/1.
  • Scenario definitions and fixtures: jans-cedarling/bindings/benchmarks/fixtures/scenarios.json.

Note: unsigned_batch_* and multi_issuer_batch_* measure the full batch call, not per-item latency.

Relative speed per scenario (x vs Rust, lower = faster)#

Ratios use each binding's full-precision mean_ns over Rust's, so they may not match dividing the rounded µs values shown above. Rows where Rust is unavailable use the fastest binding as the baseline.
