How to Enable Brotli and Gzip Compression in Nginx on RHEL 8 — step-by-step RHEL 8 tutorial on Progressive Robot

How to Enable Brotli and Gzip Compression in Nginx on RHEL 8

Compression reduces the byte size of HTTP responses, lowering bandwidth consumption and improving page load times. Nginx ships with built-in Gzip support through ngx_http_gzip_module, but Gzip has largely been superseded by Brotli for text content — the Brotli algorithm typically achieves 15–25% better compression ratios at equivalent CPU cost. On RHEL 8, Gzip requires only […]
