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

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
