title: Memcache or Memcached installation for Drupal?
body: <p>I've been floating around the Google and everything's getting more confusing now. What i want to know is how to install <code>Memcache</code> or <code>Memcached</code>. Even which one to install, i'm still not sure. It is super confusing.</p>
  
  <p>I'm on Redhat RHEL. Actually i have installed <code>Memcached</code> (with 'd`) on my Web Server. Then according to the articles, i enabled Php Extension, etc. Then what is supposed to happen? Totally no improvement in performance.</p>
  
  <p>Then i feel thats not enough and i googled again. Some say to install on MySQL Server. So what about PHP Extension and Drupal Module which are supposed to be configured, if i install it on MySQL Server? I'm really not getting it.</p>
  
  <p>So i have Drupal 7 and please let me know in simple way for which is the right one to follow :(</p>
  
  <ul>
  <li><code>Memcache</code> or <code>Memcached</code> ? (Why this two so confusing?)</li>
  <li>Where to put at?</li>
  <li>Does it really need Drupal Module to work?</li>
  </ul>
  
  <p>Please simply give me a straight dummy guide :(</p>
