title: OTRS slow performance main queue listing
body: <p>we have the problem of a very slow queue listing. If there are more than 15 tickets in a single queue it takes up to 4-5 seconds for creating the view.</p>
  
  <p>This problems occure since we're using OTRS 3.1
  We are running OTRS 3.1.4 with the KIX4OTRS extension on a virtualized Ubuntu 10.04 LTS.</p>
  
  <p>We tried yet:</p>
  
  <ul>
  <li>known performance tweaks provided in the manuals. </li>
  <li>creating extra database indexes</li>
  <li>installation on physical machines (no positive effects) with Ubuntu
  12.04 / 12.04.1</li>
  </ul>
  
  <p>Any ideas?</p>
