Gzip Compression Disabled

What This Rule Checks

This rule checks whether gzip compression is enabled.

Why It Matters

Gzip compression reduces the size of text-based responses (HTML, CSS, JavaScript, JSON) by 60-80%. This significantly reduces bandwidth usage and improves page load times, especially on slower connections.

✗ Bad — Triggers this rule

server {
    listen 80;
    server_name example.com;
    # gzip is off by default
}

✓ Good — Passes this rule

server {
    listen 80;
    server_name example.com;

    gzip on;
    gzip_vary on;
    gzip_min_length 1024;
    gzip_types text/plain text/css application/json application/javascript text/xml;
}

How to Fix

Enable gzip in Configen's Performance section. The generator will add optimized gzip settings automatically.
