On November 6–7, 2024 the 15th edition of the Symposium on Software Performance was held in Linz—organized and hosted by the JKU/Dynatrace Co-Innovation Lab, a collaboration between the LIT CPS Lab and Dynatrace Research. It brought together researchers and practitioners with a shared interest in all facets of software performance, ranging from modeling and prediction to monitoring and runtime management. This edition attracted over 50 participants from 16 affiliations, including well-known educational and research institutions from Austria, Germany and Denmark as well as prominent industry companies.
The two-day symposium program featured 30 technical research talks on topics such as performance modelling, simulation, monitoring, benchmarking and visualization. The authors of 27 of these talks submitted short research papers, which will be published soon in GI Softwaretechnik-Trends, opens an external URL in a new window. Each symposium day started with an industry keynote. On November 6, Andreas Grabner, CNCF Ambassador and DevRel at Dynatrace, walked us through how performance engineering has evolved from ad-hoc end of the release cycle testing to continuous performance as a self-service with built-in observability through frameworks like OpenTelemetry. We learned, while the industry has advanced a lot, the anti-patterns that crashed systems 20 years ago still crash modern apps today! On November 7, Philipp Lengauer, Senior Principal Product Manager and Capability Lead at Dynatrace, gave an entertaining technical talk on "the power of the commandline: a story of shell scripting, observability, and my laziness".
Philipp gave us a deep dive into how to get shell scripts to deliver OpenTelemetry traces, metrics and logs. What started as a personal need to monitor his own bot quickly became a larger challenge to provide the best observability solution for shell scripts. Crucially, he tackled automatic context propagation over HTTP, auto-instrumentation of all available commands, auto-injection into child scripts and automatic log collection.

The symposium was organized by Sören Henning from the LIT CPS Lab as well as Mario Kahlhofer and Andriano Vogel from Dynatrace Research. We would like to thank all committee members, opens an external URL in a new window, the local organization team and all participants that contributed to the event including the authors and presenters as well as our sponsor Dynatrace. In light of this year’s symposium, we also remember our founding and long-time steering committee member, André van Hoorn, who is deeply missed.
The next Symposium on Software Performance will be held in 2025 in Kiel, Germany. Further information will soon be available at http://www.performance-symposium.org/, opens an external URL in a new window.
