Subject: CPU time Vs Number of records
Posted: Mon May 09, 2016 4:05 pm (GMT 5.5)
Dear All,
I have a VSAM file which is fairly constant volume - sort of control data.
The file is read in batch. It has around 200 K records. The file is read in batch modules via keys. If I reduce record count to 20 K (i.e. 10% of original), will the keyed reads perform faster in batch? And if yes will that be considerable improvement to CPU time?
Thanks,
Nilesh.
