This is partially caused by the lack of easily available approaches and tooling that check for performance changes. The tool Peass-CI examines performance changes by measurement and analysis of the duration of unit tests. We present a case study of establishing a continuous performance engineering process in GeoMap, a Spring based tool that allows to analyze the real estate market for real estate service and market experts. In the continuous performance engineering process, we monitored performance changes that happened during six months and derived performance improvements by code reviews and load test execution. We found that (1) continuous performance measurement gives detailed insights into performance changes and (2) performance improvements by source code changes are reproducible using performance measurement of unit tests in Peass-CI.enperformancemeasurementcontinuous performance engineering processmaintenanceText/Conference Paper
