A friend of mine that does contract work, was engaged to tweak a CICS transaction. He could only shave .1 second off of the time. 1/10 sec
However, the transaction was called millions of times, saved the company from upgrading their hardware, reduced their 4hr rolling average which saved software costs. And all for 1/10 second reduction in the CICS trans run time. Tuning programs have benefits. Amazing. Lizette -----Original Message----- >From: "Roger W.
