To establish performance baselines, you measure critical path metrics like TTFB, p50/p95 latency, and bundle size using tools such as Lighthouse or Web Vitals before making changes.

Profiling frontend render cost involves measuring baselines, identifying dominant cost buckets like render or network latency, and validating improvements with before/after comparisons.

You can identify data-access bottlenecks by profiling data pipelines and services, measuring latency across data access patterns, and prioritizing fixes for the dominant cost buckets.

Validate latency and bundle improvements by establishing baselines, applying fixes, and running repeatable before/after measurement tests in your CI or staging environment.

Yes, you can optimize both frontend and backend performance by measuring metrics like Web Vitals and p50/p95 latency across web apps, services, and data pipelines.

Measuring baselines is required to identify dominant cost buckets accurately and validate that latency and resource waste reductions actually improve performance over the initial state.
