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.

# Nginx+Unicorn best-practices congifuration guide. Heartbleed fixed.
# We use latest stable nginx with fresh **openssl**, **zlib** and **pcre** dependencies.
# Some extra handy modules to use: --with-http_stub_status_module --with-http_gzip_static_module

# Deployment structure

# SERVER:
#  /etc/init.d/nginx                             (1. nginx)

JavaScript nl2br & br2nl functions

The exchange of new line & br HTML tag could refer to PHP - nl2br() function, which uses to inserts HTML line breaks before all newlines in a string.

These JavaScript functions consider whether to use insert or replace to handle the swap.
