diff --git a/10 Tips for Optimizing NGINX and PHP-fpm for High Traffic Sites b/10 Tips for Optimizing NGINX and PHP-fpm for High Traffic Sites
 Please take a look at the original article (http://www.softwareprojects.com/resources/programming/t-optimizing-nginx-and-php-fpm-for-high-traffic-sites-2081.html) as it includes excellent configuration file examples.

 1. Switch from TCP to UNIX domain sockets:
 When communicating to processes on the same machine UNIX sockets have better performance the TCP because there's less copying and fewer context switches.

 2. Adjust Worker Processes:
 Set the worker_processes in your nginx.conf file to the number of cores your machine has and  increase the number of worker_connections.

 3. Setup upstream load balancing:
 Multiple upstream backends on the same machine produce higher throughout than a single one.

 4. Disable access log files:
 Log files on high traffic sites involve a lot of I/O that has to be synchronized across all threads. Can have a big impact.

 5. Enable GZip. 

 6. Cache information about frequently accessed files. 

 7. Adjust client timeouts.

 8. Adjust output buffers.
    
 9. /etc/sysctl.conf tuning.

 10. Monitor:
 Continually monitor the number of open connections, free memory and number of waiting threads and set alerts if thresholds are breached. Install the NGINX stub_status module.
