I will be soon setting up Simple Machines forum on a fresh Ubuntu Server 10.04 VPS. The forum software is written in PHP. I will using Nginx as the web server, and I will be following a guide to install PHP-FPM on it: http://constantshift.com/install-php-fpm-5-3-2-on-ubuntu-10-04-lucid-lynx/
But the guide doesn't really explain anything about setting up Memcached or APC for caching. After looking around the net, searching this site and searching Stack Overflow, I'm still lacking answers for how to set these up successfully.
Can anyone help with information, guides, links? Much appreciated.
