Performance engineering as a part of the development life cycle for large-scale software systems

Abstract

The author addresses the role of performance engineering throughout the entire software development life cycle. He draws experiences from successful performance engineering efforts applied to large transaction-based software projects in which multiple hundreds of thousands of lines of code were developed. The nature of the performance engineering support required by such projects changes dramatically during the middle of the development period; failure to recognize the need for this change can result in discovery of performance shortfalls too late to correct them before the system must become operational.
