Hi Ron and all, 

I have captured the strobe report for the full run of the job. I will try to 
send it to later. In addition to strobe, i snapped the below statistics of the 
job from Mainview. The report shows that the EXCP and the SSCH counts are 
almost equal. I am of the understanding that if SSCH count can be reduced it 
can help in CPU reduction. Could you please provide some direction on to reduce 
the SSCH count. 

FYI,I also tried with data CISZ of 18K, 30K and 32K. 18K and 26K look to show 
almost similar performance of taking 6.5 CPU minutes for the test files with 
32M records. 26K CISZ showed the least EXCP counts amongst all..
