Introducing PerfCompare’s Simple View

Read on mozilla.org

Summary

PerfCompare now defaults to a simplified results table that shows only the key metrics (platform, base/new values, median shift, status and change size) while hiding detailed statistics behind an “Advanced options” dropdown. The view state—including selected columns, filters, and sorting—is encoded in the URL for easy sharing.

  • Default view now shows only platform, base/new values, median movement, direction, status, and change size.
  • An "Advanced options" dropdown lets users toggle Cliff’s Delta, CLES, Significance columns and expanded row details.
  • All view settings (selected columns, filters, sorting) are encoded in the URL for shareable links.
  • Future work includes persisting advanced choices locally, propagating them to subtests, and expanding the cheat sheet.

Anyone using PerfCompare for performance regression testing benefits from quicker insight and shareable result views.

It ships as a single npm package with adapters for React, Preact, Vue, Solid, Svelte, Angular, Lit, and vanilla DOM, and can run on server or client.
