Benchmarking dashboard performance

What this post added

This post details performance benchmarking and optimization efforts for the Cloudflare dashboard, specifically focusing on the login page. Key technical contributions include reducing JavaScript payload from 10MB to 6.5MB by deduping dependencies and refactoring bloated packages, implementing code splitting by separating authenticated and unauthenticated applications to reduce initial load times, and optimizing dead-code elimination (tree-shaking) to remove unused module imports. Performance metrics like Lighthouse scores and Largest Contentful Paint were used to measure improvements.
