Measurement and Tuning of Computer Systems
註釋While a number of books have been written addressing performance analysis and evaluation topics, most of them have been written for researchers and students rather than practitioners in the field or for their managers. Others, intended for the professionals, do not adequately cover some of the areas in which the most important advances have occurred, like analytic modeling. This book emphasizes measurement techniques (which are really fundamental: without measurement, system evaluation is impossible) and tuning projects. The context of most of the discussions and of the case studies is one in which the system whose performance is to be evaluated exists and is running; in this context, one of the main goals of evaluation activities is to improve the cost-performance ratio of the installation.
