Theory and systems design concepts are applied to operating systems such as Linux, UNIX, OpenVMS, MVS, and other operating systems. After a section on performance principles and components, such as hardware and networks, sections are devoted to simple theory and concepts in performance, performance in practice, and benchmarks and benchmarking. About 170 pages of appendices give background on areas such as queuing theory, historical benchmarks, and math for performance measurement.
