We have a cloud server hosted on Rackspace with Nginx, PHP, MySQL installed that is serving a Wordpress based site. What we need is to optimize the configuration of the server and its modules to deal with heavy traffic, this will include:
1. Setting up the right memory usage and processors environment variables for NGINX, PHP, MySQL
2. Installing Varnish or equivalent caching system
3. Benchmark server performance using [url removed, login to view]
4. Any additional optimizations that are suggested.
We need to see a major increase the [url removed, login to view] reported performance as result of all of the above.
