Enabling compression

Compression is not active — enable Gzip/Brotli.

What it is

We detected that the server is not compressing responses. Enabling Gzip/Brotli transfers text files significantly smaller.

Why it matters

Disabled compression is a needless loss of speed and data. It's among the first things to address — the effect is immediate and across the board.

How to do it

  1. 1On shared hosting, look for a "Gzip/compression" toggle; often it's enough to turn it on.
  2. 2On your own server, enable mod_deflate/mod_brotli (Apache) or gzip/brotli (Nginx).
  3. 3Via a CDN (Cloudflare etc.) you can enable compression centrally.
  4. 4After enabling, verify Content-Encoding in the response.

Conclusion

See the topic "Response compression" — the principle is the same, it's just not yet enabled here. It's one of the simplest and most worthwhile changes of all; deploy it first.
