Performance of the Linux kernel is one of the key features for its users. Despite this fact, systematic testing for performance regressions is relatively scarce because of its inherent difficulty. In this presentation, Jan Kara will introduce the test framework Marvin that is used within SUSE for performance testing of both distribution and upstream kernels. He will also review tests that are regularly run by this framework. Finally he will discuss challenges of the performance testing including examples of performance regressions detected by the framework and their analysis to demonstrate those challenges.
