It's 2015, not 1985. Most people are not paying IBM for every CPU cycle (used or not) on a mainframe. Should IT staff try to look "good" on a "CPU utilization" report that belongs in a history book by buying lower-end hardware, or should they spend a tiny amount of extra money to ensure that customers get good performance during peak periods?
