title: CPU Time vs Elapsed Time in T-SQL
body: <p>From what I've read (please correct me on any of these points if I'm wrong);</p>
  
  <ul>
  <li><p>CPU time is the time that the CPU is used (i.e. without the delays caused by other resources)</p></li>
  <li><p>Elapsed time is the wall clock time (the amount of time taken to execute the operation regardless of any resource delays or multiple threads etc.)</p></li>
  <li><p>Elapsed time is generally higher than CPU time with the exception of a multi processor environment</p></li>
  </ul>
  
  <p>Assuming that the time taken by all my resources such as I/O is 0 </p>
  
  <p>Can I say that CPU Time divided by # of cores &lt;= Elapsed time ?</p>
