随着计算机系统结构的复杂性和计算机应用的复杂性的不断发展,计算机系统性能评价也迅速发展起来,并形成了计算机科学的一个重要研究领域。研究系统性能评价的根本目的就是为了研究如何更好地设计、配置和改善计算机系统,提高其成本效率,以利于各种各样的应用。本文首先综述了系统性能评价的发展,然后分别详细描述了性能评价的三个主要方法:分析、摸拟和测量,举例说明了它们的应用,并提出了我们的一些看法。 With the complexity of computer system structure and the complexity of computer application, the evaluation of computer system performance has also rapidly developed and formed an important research area of ​​computer science. The fundamental purpose of researching system performance evaluation is to study how to better design, configure and improve computer systems to increase their cost efficiency for a wide range of applications. This paper first reviews the development of system performance evaluation, and then describes the three main methods of performance evaluation in detail: analysis, simulation and measurement, illustrates their application, and puts forward some of our opinions.
