【Abstract】 The computer system performance models are used in the design and implementation of an automatic QoS controller for e-commerce sites in terms of e-commerce site’s workload. The QoS controller uses an aggregate metric index that includes response time, probability of rejection, and throughput, and executes a combinatorial optimization algorithm to search an optimal point in the space of parameter configuration values.更多还原
