Memcached is a great tool for optimising your website.  It can be used to cache commonly used data in memory for fast access.  This can help greatly in increasing speed, reducing DB load and scaling your site.  To find out more check out the memcached site here.

Open a terminal(Ctrl + Alt + T) and enter the following:

sudo apt-get install memcached

sudo apt-get install php5-memcached

sudo /etc/init.d/apache2 restart

to test memcached is up and running enter:
