Not Only Gzip
summary
Shows concrete ways to compress web assets beyond plain gzip: use Zopfli offline to get a few extra KB (very slow), adopt Brotli for static and dynamic responses (examples report ~5KB median savings, up to ~10–14KB on Bootstrap and core search HTML), and precompress .br/.gz files with nginx configured to serve them. Also demonstrates shared-dictionary compression that downloads a small dictionary once and then reduces many HTML pages by roughly 2–4×, while warning about the extra dictionary request and its CPU/memory unpack costs and limited browser support.
