本文提出一种评估交互式计算机系统的利用率,吞吐率及响应时间的方法,归纳出一组数学表达式,能描述系统参数与系统性能指标之间的关系.当需要了解现有系统性能或欲通过改变系统配置以获取更好的指标时,这些表达式能提供有用的结果或起指导作用. In this paper, we propose a method to evaluate the utilization, throughput and response time of interactive computer systems, and summarize a set of mathematical expressions that describe the relationship between system parameters and system performance metrics. When you need to understand the existing system performance or These expressions can provide useful results or guidance when changing system configurations for better metrics.
