NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

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.

Setup a Local Only SMTP Email Server (Linux, Unix, Mac)

Setup a Local Only SMTP Email Server (Linux, Unix, Mac)

1 - Point localhost.com to your machine

Most of programs will not accept an email using just @localhost as domain. So, edit /etc/hosts file to make the domain localhost.com point to your machine, including this content to the file:

127.0.0.1 localhost.com

2 - Install Postfix

Easily setup an Android development environment on a Mac

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

  • XCode is installed (via the App Store)
  • XCode command line tools are installed (xcode-select --install will prompt up a dialog)
  • Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
