Learn about Fastpath, an open-source benchmarking tool developed by Arm, in this 28-minute conference talk from the Linux Plumbers Conference. Discover how this tool addresses the current gaps in kernel performance testing by providing shared tooling and common practices for benchmarking. Explore the challenges facing upstream kernel quality efforts, which have traditionally focused on functional testing while performance testing has lacked standardized approaches. Understand how Fastpath aims to generalize benchmarks and offers a comprehensive front-end for data storage and analysis, with particular emphasis on identifying and bisecting performance regressions across various benchmark collections. Gain insights into improving kernel performance testing practices and learn about the tool's potential to enhance the overall user experience by making performance benchmarking more accessible and systematic.
