SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Performance optimization without measurement is guessing — profile first and measure improvements before changing code.

Core Features & Use Cases

  • Measurement-driven workflow: measure, identify bottlenecks, fix, verify, guard against regression.
  • Frontend and backend scope: focused on Core Web Vitals (LCP, INP, CLS) and API latency; supports detection of bottlenecks and validation.
  • Use Case: When a release causes slower load times or degraded user experience; when there are slow endpoints or heavy data processing tasks requiring targeted optimizations.

Quick Start

Run an initial performance audit to establish baseline metrics, identify the top bottleneck, implement a measured fix, and re-run measurements to verify improvement.

FAQPage Schema
How do I fix Core Web Vitals when my web app has slow load times?▼

To fix Core Web Vitals, run an initial performance audit to establish baseline metrics for LCP, INP, and CLS, identify the top bottleneck, implement a measured fix, and re-run measurements to verify improvement.

What is the best way to identify frontend and backend performance bottlenecks?▼

The best way to identify performance bottlenecks is using a measurement-driven workflow that profiles frontend metrics like LCP and backend API latency to pinpoint slow endpoints and heavy data processing tasks.

How do I stop performance regressions after a new release?▼

To stop performance regressions, enforce a measurement-first workflow that guards against regression by verifying fixes with re-runs of performance audits and continuously monitoring Core Web Vitals after release.

Why does my web app need profiling before changing code to improve performance?▼

Your web app needs profiling before changing code because performance optimization without measurement is guessing; profiling establishes baseline metrics to identify actual bottlenecks and verify improvements.

Can I optimize both frontend Core Web Vitals and backend API latency together?▼

Yes, you can optimize both frontend Core Web Vitals and backend API latency together using a measurement-driven workflow that profiles LCP, INP, CLS, and backend timing to identify and fix regressions across the stack.
