[net] 91a760b269: stress-ng.sockfd.ops_per_sec 11.1% improvement

by kernel test robot

Greeting, FYI, we noticed a 11.1% improvement of stress-ng.sockfd.ops_per_sec due to commit: commit: 91a760b26926265a60c77ddf016529bcf3e17a04 ("net: bpf: Handle return value of

[sched/fair] c9c342d546: fxmark.ssd_xfs_DWOM_72_bufferedio.works/sec -58.3% regression

by kernel test robot

Greeting, FYI, we noticed a -58.3% regression of fxmark.ssd_xfs_DWOM_72_bufferedio.works/sec due to commit: commit: c9c342d5463edc3fbf808db485570b1803b6eefe ("sched/fair: Relax update_min_vruntime()") https://git.kernel.org/cgit/linux/kernel/git/peterz/queue.git sched/wip.migrate in testcase: fxmark on test machine: 24 threads 1 sockets Intel Atom(R) P5362 processor with 64G memory with following parameters: disk: 1SSD media: ssd test: DWOM fstype: xfs directio: bufferedio cpufreq_governor: performance ucode: 0x9c02000e test-description: FxMark is a filesystem benchmark that test multicore scalability. test-url: https://github.com/sslab-gatech/fxmark In addition to that, the commit also has significant impact on the following tests: If you fix the issue, kindly add following tag Reported-by: kernel test robot <oliver.sang(a)intel.com> Details are as below: --------------------------------------------------------------------------------------------------> To reproduce: git clone https://github.com/intel/lkp-tests.git cd lkp-tests sudo bin/lkp install job.yaml # job file is attached in this email bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run sudo bin/lkp run generated-yaml-file # if come across any failure that blocks the test, # please remove ~/.lkp and /lkp dir to run from a clean state.
