Response compression enabledlow impactlow effort
no content-encoding header
This HTML is served uncompressed, so every visitor downloads far more bytes than necessary — text compresses extremely well, and the savings directly speed up first render on slow connections. Enable Brotli or gzip on your server or CDN: in nginx it's "gzip on;" (or the brotli module), in Apache it's mod_deflate via .htaccess, and on most CDNs it's a single toggle. Make sure compression covers all text types (HTML, CSS, JS, JSON, SVG), but skip already-compressed images — recompressing them wastes CPU for no gain.
