title: Problem with cds.RecordCount
body: <p>Is there a problem with cds.RecordCount ?</p>
  
  <p>I usually use it to determine if I have any records in a query.</p>
  
  <p>But talking with a college he told that there is a performance penalty to that!</p>
  
  <p>I have made some test and nothing major came up.</p>
  
  <p>So is there a performance penalty or any other problem with RecordCount?!</p>
  
  <p>If so, what is the best way to check if there are some records in a query?</p>
  
  <p>Thanks</p>
