Chapter 1. Perspectives on Performance Management

Chapter 1. Perspectives on Performance Management

Our goal in writing this book is to provide a good introduction to the Windows 2000 operating system and its hardware environment, focusing on understanding how it works from the standpoint of a performance analyst responsible for planning, configuration, and tuning. Our target audience consists of experienced performance analysts, system administrators, and developers who are already familiar with the Windows 2000 operating system environment.

Taken as a whole, Windows 2000 performance involves not just the operating system, but also the performance characteristics of various types of computer hardware, application software, and communications networks. The key operating system performance issues include understanding CPU scheduling and multiprogramming issues and the role and impact of virtual memory. Key areas of hardware include processor performance and the performance characteristics of I/O devices and other peripherals. Besides the operating system (OS), it is also important to understand how the database management system (DBMS) and transaction-monitoring software interact with both the OS and the application software and affect the performance of applications. Network transmission speeds and protocols are key determinants of communication performance. This is a lot of ground to cover in a single book, and there are many areas where our treatment of the topic is cursory at best. We have compiled a rather lengthy bibliography referencing additional readings in areas that we can discuss only briefly in the main body of this book.
