We're enhancing some processes and converting to ARITH(EXTEND) as a
result of increased field lengths. Initial testing is showing about a 30%
increase in CPU time.
Has anyone else done this conversion and experienced similar performance
degradation ????
I expect a certain performance hit, but this seems high to me. I also note this
old post on the same subject. Where can I find a copy of this "COBOL
Performance Tuning" document ???
Thanks again,
