Modern Text Compression: Brotli
Brotli is a compression algorithm optimized for web formats. Compared to Gzip, Brotli achieves 15-20% higher compression ratios for CSS, JS, and HTML files, reducing TTFB and payload transfer times.
Lazy Loading Assets
De-prioritize offscreen content. Add `loading="lazy"` to images and iframes so the browser only requests them when they approach the viewport, saving user bandwidth and improving initial LCP.
