10th Symposium on Software Performance (SSP) Würzburg, November 5-6, 2019: Preface

Abstract

Around fifty participants from Karlsruhe, Würzburg, Stuttgart, München, Kiel, Nürnberg, Leipzig, Hannover, Ulm, Mannheim, Linz and Hildesheim attended the 10 year anniversary edition of the Symposium on Software Performance in Würzburg. Performance is one of the most relevant quality attributes of any IT system. While good performance leads to high user satisfaction, weak response times lead to loss of users, perceived unavailability of the system, or unnecessarily high costs of network or computing resources. Therefore, various techniques to evaluate, control, and improve the performance of IT systems have been developed, ranging from online monitoring and benchmarking to modeling and prediction. Experience shows, that for system design or later optimization, such techniques should be applied in smart combination. Therefore, the "Symposium on Software Performance" brings together researchers and practitioners interested in software performance, where performance is understood both in classical sense as the amount of useful work accomplished by a software system compared to the time and resources used", as well as in a broader sense as "the manner in which or the efficiency with which a software system reacts or fulfills its intended purpose". The scope of the symposium spans measurement, modeling, benchmark design, and run-time management. The focus is both on classical performance metrics such as response time, throughput and resource utilization, as well as on the relationship of such metrics to other software quality attributes including but not limited to scalability, elasticity, (energy) efficiency, dependability (in terms of availability and reliability), resilience, security and privacy.
