The code is<br>multi-threaded and fairly well balanced, hence, the total CPU numbers<br>are about 2X the elapsed time numbers.<br><br>64 bit:<br> Elapsed time: 59.316 sec<br> Total CPU time: 112.43 sec<br><br>32 bit:<br> Elapsed time: 59.749 sec<br> Total CPU time: 105.67 sec<br><br><br>I would be glad to run other comparisons if anyone would like them.<br><br>Buddy Coffey<br>Applied
