Does Cobol linear search provides better performance against Perform
Until
My isssue is -
I have a cobol program which was changed from Binary search to to
Perform Until to handle and process muliple occurances of search key.
This is a requirement that I will have multiple occurances for the
search key.

After the change my program performance deteriorate, which is, very
well expected, but the magnitude is 12 to 13 times more. Earlier, I
had my data processed in 10 CPU minutes and now it takes about 130 CPU
minutes.

Any suggestion. Please help

Thanks
Aru
