Detection and solution of software performance antipatterns in palladio architectural models

Abstract

Antipatterns are conceptually similar to patterns in thatthey document recurring solutions to common design problems.Performance Antipatternsdocument, from a performance perspective, common mistakes madeduring software development as well as their solutions.The definition of performance antipatterns concerns softwareproperties that can include static, dynamic, and deploymentaspects. Currently, such knowledge is only used by domain experts;the problem of automatically detecting and solving antipatternswithin an architectural model has not been experimented yet.In this paper we present an approach to automatically detect and solvesoftware performance antipatterns within the Palladio architectural models:the detection of an antipattern providesa software performance feedback to designers, since it suggeststhe architectural alternatives that actually allow to overcomespecific performance problems. We implemented theapproach and a case study is presented todemonstrate its validity. The system performance under studyhas been improved of 50\% by applying antipatterns' solutions.
