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 ??? *********************************************************************** Bear Stearns is not responsible for any recommendation, solicitation, offer or agreement or any information about any transaction, customer account or account activity contained in this communication. *********************************************************************** ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
