title: Analyzing query statistics in PhpMyAdmin
body: <p>I'm trying to analyze my MySql database and server and when looking in phpmyadmin Status->Query statistics I can see that these three queries are the most used:</p>
  
  <pre><code>set option 31.91%
  change db 15.71%
  show variables 15.83%
  </code></pre>
  
  <p>I'm quite a newbie in MySql and my question is now: Why are these queries running so often? SELECT, INSERT, UPDATE and DELETE are not at all that frequently running on the server. I just wanted to see if this is normal behavior?</p>
  
  <p>Thanks for your help!</p>
