Performance teams need to detect regressions by establishing baselines for page load times, Core Web Vitals, and resource sizes, then compare new builds against those baselines.
Run /benchmark <url> to start a full performance audit and baseline comparison.

You can detect web performance regressions by running a benchmark audit on the target URL to collect current metrics and compare them against stored baselines. The tool automates this comparison for PR workflows to surface key metric degradations.
Establishing a performance baseline for Core Web Vitals requires capturing key page load metrics and resource sizes during a stable build. The tool writes this baseline data to a local directory for future regression comparisons.
You can track historical performance trends by running full-site audits that store baseline metrics over time. This process surfaces gradual regressions by comparing new build results against previously exported JSON data.
Yes, you can benchmark specific page sets rather than a full website. The tool includes page selection modes and quick timing options to target and compare performance metrics for defined subsets of URLs.
Performance benchmark baselines are stored locally in the .nexus/benchmark-reports directory. The tool writes baseline data to this location and exports JSON files to facilitate historical trend analysis and regression tracking.
