It is important to look at the Elapsed times, not just the CPU times.  If a
system is not tuned correctly, although the CPU times may be low, the total
time from start to completion may be high which is what someone doing similiar
work probably cares about.

From the 5/7/91 ANSYS Report,  the SP-3 times for the HP are

             CPU      ELAPSED

    720       66       121
    730       48       109
