1. Preface
Almost 40 participants from Germany and Czech Republic have attended the 12th Symposium
on Software Performance (SSP). Despite the Covid-19 pandemic, it was possible to hold the
symposium as physical event.
Performance is one of the most relevant quality attributes of IT systems. While good perfor-
mance leads to high user satisfaction, weak response times lead to perceived unavailability of
the system, or unnecessarily high costs of network or computing resources, or may even cause
a loss of users. 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 subsequent optimization,
such techniques should be applied in smart combination.
For these reasons, the SSP brings together researchers and practitioners interested in all
facets of software performance, ranging from modeling and prediction to monitoring and
runtime management. The symposium is organized by the three established research groups
Descartes [1], Kieker [2], and Palladio [3]; thus this symposium also serves as a joint community
meeting. Descartes’ focus are techniques and tools for engineering self-aware computing
systems designed for maximum dependability and efficiency. Kieker is a well-established tool
and approach for monitoring software performance of complex, large, and distributed IT systems.
Palladio is a likewise-established tool and approach for modeling software architectures of IT
systems as well as for simulating their performance.
The symposium program includes contributions from practitioners and researchers in the
field of software performance, including but not limited to approaches employing Descartes,
Kieker, or Palladio.
In addition to the three organizing groups, the SSP is also supported by the special inter-
est group “Softwaretechnik” (software engineering) of the “Gesellschaft für Informatik (GI)”
and by the special interest committee “Messung, Modellierung und Bewertung (MMB) von
Rechensystemen” (measurement, modeling, and evaluation of computer systems) of GI and the
“Informationstechnische Gesellschaft ITG im VDE”.

We solicited two types of contributions, namely technical papers and posters for industry
or experience talks. Submitted proposals were reviewed by a program committee with the
following members:
• Holger Eichelberger, University of Hildesheim
• Johannes Grohmann, University of Würzburg
• Robert Heinrich, KIT
• Reiner Jung, Kiel University
• Holger Knoche, ivv GmbH
• Sebastian Krach, FZI
• Johannes Kroß, Fortiss GmbH
• Dušan Okanović, Novatec Consulting GmbH
• David Georg Reichelt, Leipzig University
• Norbert Schmitt, University of Würzburg
• Henning Schnoor, Kiel University
• Dominik Werle, KIT
The program committee was chaired by:
• David Georg Reichelt, Leipzig University
• Richard Müller, ipoque GmbH
Currently, the steering committee has the following members:
• Steffen Becker, University of Stuttgart
• Wilhelm Hasselbring, Kiel University
• André van Hoorn, University of Stuttgart
• Samuel Kounev, University of Würzburg
• Anne Koziolek, KIT
• Ralf Reussner, KIT/FZI
We would like to thank all committee members, the local organization team, and all partici-
pants that contributed to the event including the authors and presenters as well as our sponsors
RETIT GmbH, Appsfactory GmbH, Novatec Consulting GmbH and GISA GmbH.
