Why is it so hard to predict if a code change will improve (or reduce) the performance of a system? Why do even mature, IT-savvy companies such as Meta, Mozilla, or MongoDB Inc. struggle to foresee performance regressions before rolling out a change? Why does it feel like all software is constantly getting slower, not faster? In this talk, I will talk about the minefield that is performance measurement and prediction. I will talk about the factors influencing software performance, the challenges of correctly measuring the performance of even simple code, and discuss why machine learning and large language models failed to provide the simple answers we were all hoping for.
Philipp is an Associate Professor of Software Engineering at Chalmers and the University of Gothenburg, Sweden, where he leads the Internet Computing and Emerging Technologies Lab (http://icet-lab.eu/). He is currently also the head of the Software Engineering 2 unit, consisting of 6 faculty and various doctoral students and postdocs across both universities. Philipp’s primary research interest is in software performance estimation and improvement, particularly in a web- and cloud development context. Moreover, Philipp is interested in empirical and experimental software engineering research, and generally in how to improve developer experience and productivity..
