Cary, In a TKPROF report, there is a small table at the top. It includes a column for CPU time and another for Elapsed Time.
Suppose the total line shows CPU = 3.00 and elapsed = 5.00. You would think that the two seconds difference would be for waits, but that doesn't seem to be true. Since you have investigated trace files quite a bit, do you have an idea what these two TKPROF totals actually represent? If the difference between these two isn't waits, what is it? >From a pragmatic point of view, if all I have is a TKPROF report is there anything useful I can learn from seeing these two totals?
