"The central server model is used to extend Buzen's results on balance and bottlenecks. Two measures are developed which appear to be useful for evaluating and improving computer system performance. The first measure, called the balance index, is useful for balancing requests to the peripheral processors. The second quantity, called the sensitivity index, indicates which processing rates have the most effect on overall system performance."@en . . "Central processing units." . . . .
