This report documents the program and the outcomes of Dagstuhl Seminar 25341 on software performance engineering. This seminar convened researchers from diverse intellectual communities across computer science to synthesize a collective understanding of this fragmented discipline and advance software performance engineering as a rigorous and principled scientific field in its own right. With connections established by this seminar, we are creating a unique arena for computer science researchers to cross-fertilize by sharing performance-engineering tools, techniques, opportunities, challenges, and open problems in their own domains of expertise. The major activities included 29 talks on recent research, five working groups that discussed topics like tools, community-building, education, and LLMs, and three "world cafe" sessions with in-depth conversations among participants on guiding questions for advancing software performance engineering.
