Context: Debugging performance bugs in configurable software systems is a complex and time-consuming task that requires not only fixing a bug, but also understanding its root cause. While there is a vast body of literature on debugging strategies, there is no consensus on general debugging strategies. This makes it difficult to provide concrete guidance for developers, especially for debugging configuration-dependent performance bugs.

Objective: The goal of our work is to alleviate this situation by providing an framework to describe debugging strategies in a more general, unifying way.

Method: To this end, we conducted a user study with 12 professional developers who debugged a performance bug in a real-world configural system. To observe developers in an unobstructive way, we provided them with an immersive virtual reality tool, SoftVR, giving them a large degree of freedom to choose the preferred debugging strategies.

Result: The results show that existing strategies are too coarse-grained and intermixed to identify successful approaches. In the subsequent qualitative analysis, we developed a coding framework to reason about debugging approaches. With this framework, we identified five goal-oriented episodes that developers employ, which they also confirmed in subsequent interviews.

Impact: Our work provides guidance on a unified description of debugging strategies, allowing researchers a common base to study debugging and practitioners and teachers guidance on successful debugging strategies.
