Memcached

Implementing Memcached to improve your application's performance can be done fairly quickly without using
 Zend Framework. If you're just wanting Memcached, you don't necessarily need Zend Framework. On the 
other hand, if you're using Zend Framework but you're not using Memcached, this will help you get things 
going. But whatever your situation: If you're not already using Memcached, start tomorrow.
