Below are two extracts from a log for two processes which are different in method but the same in aim.

Process A

CPU time - 00:00:00.92 Elapsed time - 00:00:07.05 Vector affinity time - 00:00:00.00 Vector usage time - 00:00:00.00 RSM Hiperspace time - 00:00:00.00 EXCP count - 544 Task memory - 3675K (130K data, 3545K program) Total memory - 17482K (6048K data, 11434K program)

Process B

CPU time - 00:00:00.67 Elapsed time - 00:00:04.78 Vector affinity time - 00:00:00.00 Vector usage time - 00:00:00.00 RSM Hiperspace time - 00:00:00.00 EXCP count - 533 Task memory - 3902K (888K data, 3014K program) Total memory - 17482K (6048K data, 11434K program)

Question: in terms of memory which is the best? My expectation was that Process A would use less memory than B, and if I look at Task Memory then this is true, but in both instances Total Memory is the same and according to Michael Raithels book "Tuning SAS Apps..." this is "...the total amount of memory that was required to complete the task." So is process A any better than B in this regard?
