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.

Install Direwolf

The official Direwolf User Manual uses MacPorts to manage installation and dependencies. I don't particularly like MacPorts, so here are some instructions for installing Direwolf via Homebrew.

Overview

This document describes how to compile GQRX using native OSX Qt 5 and libraries from brew.

	Once you have found some TETRA signals, record their frequencies. Now close SDR#, or whatever software you were using and boot into Linux. In this tutorial we use a 32-bit Ubuntu 14.04 virtual machine running on VMWare Player as our Linux system. Some of the commands may vary if you are using a different system.


	Install the software
	Note: There is now a telive live Linux image available. This will allow you to boot via a USB drive straight into a Linux OS with telive preinstalled. If you want the easy way out, or have trouble with the install script below, then try this image.

	Note 2: As of October 2016 there is now a Windows port of the Telive decoding software available. This may be an option for you if you prefer to run in Windows. More information here.

	This install script will automatically download the software and all the required prequisites including the RTL-SDR drivers. If you have problems consult the documentation or try a manual install. Instructions for the manual install are shown at the en
