Chapter 16 SOFTWARE PERFORMANCE ENGINEERING

Abstract: Performance is critical to the success of today’s software systems. However, many software products fail to meet their performance objectives when they are initially constructed. Fixing these problems is costly and causes schedule delays, cost overruns, lost productivity, damaged customer relations, missed market windows, lost revenues, and a host of other difficulties. This chapter presents software performance engineering (SPE), a systematic, quantitative approach to constructing software systems that meet performanced objectives. SPE begins early in the software development process to model the performance of the proposed architecture and high-level design. The models help to identify potential performance problems when they can be fixed quickly and economically. Key words: performance, software performance engineering, architecture 1
