The method in which I've acheived the most success in these types of scenarios was to model. Not to run a commercial, Best/1 was my tool of choice. In this manner you can take your actual workload and do different what if cases and see pretty accururately how your environment will perform after the change.
Good luck. ---------------------------------------------------------------------- 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
