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.

Stable version NGINX (deb/rpm)

#Creating your own Gem

Run this command in your Terminal. This creates and names all the files you need for your gem. We are going to create a Lorem Ipsum Generator; you can call it whatever you want but seeing as we are creating a Lorem Ipsum generator we'll call it lorem. Read about gem naming conventions.

This is my guide to web dev. There are many like it, but this one is mine.

# same as 'my.messages.hello'
