NGINX Performance Tuning

Content Compressions and Decompression

  • Documentation
    • NGINX http_gzip module
    • NGINX http_gunzip module
  • Enable gzip. by default, we’re not going to compress the responses that we’re getting from proxied servers or any piece of content that isn’t HTML.
  • But if one of our proxied servers happens to send us a pre-compressed response then we probably want to decompress it for clients that can’t handle gzip. In this situation, we’ll use the gunzip module 
    $ vim /etc/nginx/nginx.conf

# uncomment gzip module
gzip on;
gzip_disable msie6;
gzip_proxied no-cache no-store private expired auth;
gzip_types text/plain text/css application/x-javascript application/javascript text/xml application/xml application/xml+rss text/javascript image/x-icon image/bmp image/svg+xml;
gzip_min_length 1024;
gzip_vary on;
gunzip on;
    • Expanation:
      • gzip_disable - Ensure that we’re not sending compressed responses to older versions of Internet Explorer (hopefully no one is actually using these browsers)
      • gzip_proxied - Specify that we only want to compress responses from proxied servers if we normally wouldn’t cache them
      • gzip_types - The Content-Types that we will compress before sending the response
      • gzip_min_length - Adjusting the minimum size of a file that we’ll compress, the default is 20 bytes, but we’re going to not compress resources that are less than one kilobyte
      • gzip_vary - Adds a Vary: Accept-Encoding header. This tells intermediate caches (like CDNs) to treat the compressed and uncompressed version of the same resource as 2 separate entities
