An example of 1 job run on each version:
MPP 6.6.0 - took 28 minutes
MPP 6.4.3 - took 8 minutes - 3.5 times faster
In the MPP 6.6.0 release with a new AcuCobol compiler and updated software to perform better duplicate elimination, there are now more instructions in the MPP 6.6.0 software. With more instructions per each attempt for a duplicate elimination, the job will take longer.
