Identifying Bottlenecks in a Visualization Platform for Tracing Adaptation Decisions
(Softwaretechnik-Trends Band 39, Heft 4, 2019) Pfannemüller, Martin; Becker, Christian
Measuring the performance of different operations as part of a software system can help to identify performance bottlenecks. This information can be used to improve the performance of the monitored system. In previous work, we proposed a visualization platform for observing and understanding adaptation decisions in self-adaptive systems. In this paper, we apply Kieker as a monitoring solution to measure the runtime of different operations based on the granularity of methods and tasks. As a result, we identified possibilities for improvements in our implementation.

Performance analysis of a virtualized vehicle-compute platform: An experience report
(Softwaretechnik-Trends Band 39, Heft 3, 2019) Hesse, Christopher; Welsch, Tim; Eichelberger, Holger
Compute platforms for modern automotive systems tend to combine embedded properties, increasingly complex architectures and even virtualization. However, analyzing the performance of such systems, e.g., to identify performance bottlenecks, is not trivial. In this paper, we report our experience in analyzing the performance of a camera-vision application on a virtualized vehicle-compute platform. We discuss issues that we faced during the analysis, impacts of the virtualization on the performance as well as causes.
