Measurement and rating of computer systems performance and of software efficiency

Meer over het boek

ISO has introduced a new method for describing and measuring performance across various data processing systems and applications, addressing the challenges posed by numerous incompatible methods and terms. This method is outlined in the International Standard ISO/IEC 14756. The textbook caters to both performance experts and novices, as well as academic users, presenting the latest performance measurement techniques while also serving as a guide for applying the standard. It includes two advanced aspects: a rating method for computing user-required performance values (reference values) and a process for comparing these with actual measurements to determine if user requirements are met. Additionally, the standard extends its methodology to evaluate the run-time efficiency of both application and system software, providing a framework for quantifying and measuring this property. Each chapter delves into specific performance measurement aspects, supplemented with exercises and provided solutions. Since manual measurement is impractical, the book includes necessary software tools on a CD, published under GNU license. While not designed for professional measurements, this software allows readers to execute all steps involved in performance or software efficiency measurement.
