OpenWebF App: Performance (JavaScript Side)

Instructions

  1. Establish a measurement baseline (prefer production builds for accuracy).
  2. Add minimal instrumentation (performance.mark/measure) around suspected hot paths.
  3. Apply high-leverage best practices:

- reduce sync work on critical path - debounce expensive operations - split bundles and monitor size

  1. Use MCP docs for recommended practices and code snippets.

If the user’s question is primarily about host-side FP/FCP/LCP wiring or dumpLoadingState, prefer openwebf-host-performance-metrics.
