title: DBUnit: Depends the time to import a XML file on the delta?
body: <p>I analyze a test automation framework and the goal is to speed it up.</p>
  <p>In this framework DBUnit will be used to bring database in a specific state. During the analysis I recognized the following:</p>
  <ul>
  <li>The time to import a DBUnit XML file has nothing to do with the file size</li>
  <li>The bigger the delta between the current database status and the status the XML file will create, the longer takes the import</li>
  </ul>
  <p>Can anyone confirm or veto that, please?</p>
  <p>If this is true, would it be faster to empty the database and apply the import file then? (No updates or deletes needed, only inserts.)</p>
  <p>If this is false, what is the real reason for the import time?
  And is there any other way to speed up the import? (Performance tips from DBUnit website are already in place.)</p>
  <p>Thank you for your help!</p>
