PerfMinerArch - A Tool to Visualize and Analyze Performance Deviations

This paper presents PerfMinerArch, a tool to visualize and analyze performance deviations from subsequent evolutions of a software system. It provides architecture views that allow developers to identify scenarios and system packages/modules that have variations in their performance. It also allows exploring performance deviations of each scenario to a more detailed perspective that shows the methods and commits in repositories that are responsible for them. The tool has been applied to identify performance deviations in existing open-source software systems.
