Scope and metric definitions
Methodology and robustness
Only metrics present in both runs are compared. No missing value is imputed. Browser identity checks cover Chromium, CPU, architecture, platform and throttle where recorded; JVM checks cover runtime and OS. Sample distributions are retained in source JSON, while this report compares medians.
Limitations
- Percentage thresholds are practical noise guards, not confidence intervals.
- Results from different machines, browser builds, throttle settings or JVMs are blocked by default.
- A filtered run can compare only its common subset; aggregate changes state the number of included scenarios.
- Bundle size comparisons are deterministic for identical build inputs; runtime measurements are not.
Recommended next steps
- Inspect the largest same-environment regressions in the metric tables and raw samples.
- Repeat surprising runtime changes with more iterations before accepting a baseline.
- Promote and update documentation only from a complete all-framework run.
Further questions
Do the largest deltas reproduce in a second run, and do CPU profiles or allocation traces explain them?
