title: sp duration does not equal the sum of statement duration in sql profiler
body: <p>I have a sp which takes over 6000 ms in sql profiler, but when I looked at the statement execution duration in this sp, most of them are 0, the sum of statement execution time is far less than 6000, i have no idea where the 6000ms come from... Please help! </p>
  
  <p>Thanks! </p>
