title: When to use memcached
body: <p>I`m planing to use memcached in one of my websites. 
  Here is from memcached home page</p>
  
  <blockquote>
    <p>Memcached is an in-memory key-value
    store for <strong>small</strong> chunks of arbitrary
    data</p>
  </blockquote>
  
  <p>I consider to use memcached in search/result page where every query returns about 4kb (text).</p>
  
  <p>In this case is it reasonable to use memcached ?</p>
