9.1 Performance Mindset

Performance considerations should influence technical decisions throughout the development process rather than being addressed only at the end of a project. This means considering the performance implications of third-party integrations, image usage, JavaScript libraries, and database queries as we build features.

We measure performance using real-world metrics that matter to users, not just technical benchmarks. Core Web Vitals provide excellent guidance for performance optimization, focusing on loading speed, interactivity, and visual stability.
