I did a million record Cobol sort months ago. Here I am talking about getting the Cobol sort to work.
Saw no mention of timings on my log.
So found old Jobstream and reran today for timings.
Input 1 million 165 byte records
Output 1 million 60 byte records
Sorted by Last Name, First Name
Below is a cut & paste from the output jobstream.
SORT01 – STARTED – TIME=17.26.26
SORT01 – ENDED – TIME=17.26.39
So 13 seconds
Buried in this post I mention that I sorted 1 million records, and did some calculations using gnuCobol in less than 3 seconds. Now you would expect a native program to be faster than an emulated program. Still I like these comparisons. I think the old mainframe COBOL program performed respectively under the circumstances. No doubt running much faster on my desktop than on million dollar hardware…back in the day!
