090703 - As a result of poor performance by Supersort on c13 reported 010202,
090704 - ref SDS 39 QL5K, and failure of corrective efforts on 010214,
090705 - ref SDS 47 QL5K, submitted ref DIT 1 0001 to Opt Tech Data Processing

090717 - Explain problem....

090719 - Supersort on a P4 1.4 GHz 400 MHz bus system takes 13 seconds to
090720 - execute a selection spec on a 10 MB file, under w2k running in a
090721 - DOS window. The same operation under w2k in a DOS window on a
090722 - PIII 650 MHz computer takes only 1 second to do the same thing, as
090723 - reported on 010202. ref SDS 39 QL5K
090724 -
090725 - Does Opt Tech Sort have a similar drop off in performance using a
090726 - P4 faster environment?
