Introduction to Software Performance Engineering

摘要

Most software performance problems are due to fundamental architecture or design problems. Thus they are introduced early in development, but are typically not discovered until late, when they are more difficult and costly to fix. This tutorial presents a systematic, quantitative approach for cost-effectively building performance into software systems. It reviews the purpose of Software Performance Engineering (SPE) and the steps for applying the SPE methods throughout the life cycle of new systems. It describes the data required for SPE studies. It reviews the software and system execution models for assessing the performance of alternatives and for capacity planning for new applications.
