UML-based performance engineering possibilities and techniques

An information system´s performance in relation to time and resources is largely determined by the design selected in software development. Performance engineering´s core concept accounts for a software system´s performance from the earliest development phases. Unfortunately, these measures are not performed explicitly during software development, primarily because of deadline pressure, the information system´s complexity, or lack of knowledge of what PE means. The authors overview UML-based PE, analyze corresponding approaches, and examine the advantages of the tools available
