Modern browsers support `gzip`, improving download time and data usage. To resolve this, enable and test `gzip` on your server, using tools like `mod_deflate` for Apache, `ngx_http_gzip_module` for Nginx, or configure HTTP compression in IIS. Proxy servers or anti-virus software can interfere with compression, impacting PageSpeed Insights' results.\n"]]
