Hi Josef and all, I would like to be rude and solicit a talk from Josef on automated performance regression testing (if he is planning to attend). We know the guys at facebook are running some performance regression tests for a while and Josef has just upstreamed a nice taste on this infrastructure to xfstests: https://marc.info/?l=fstests&m=150765617921864&w=2 But this is only the beginning... for community performance regression tests to be useful there need to be not only people running the tests, but also people running the tests on well known machines and/or well known hardware configurations and maintain long lived performance results db for those machines. How can we utilize community resources to achieve that? Can running performance regressions of gce-xfstests provide anything close to stable results? If performance regressions are integrated into 0-day kernel test robot, that could be extremely beneficial to the community, but can the robot guaranty to run the tests on dedicated machines or VMs with dedicated resources? Do we know of good examples to follow from automated regression tests done for specific filesystem (Dave Chinner has referred to his regression tests in one or two occasions)? for other kernel subsystems? Putting up a regression test server for overlayfs is on my TODO list. In the mean while, I have little to contribute from my experience, but would love to sit in that talk. Cheers, Amir.
