<linux-kernel@...r.kernel.org>, linux-kernel@...r.kernel.org, lkp@...org Subject: [lkp-robot] [sched/fair] 806486c377: fsmark.app_overhead 39.4% improvement Greeting, FYI, we noticed a 39.4% improvement of fsmark.app_overhead due to commit: commit: 806486c377e33ab662de6d47902e9e2a32b79368 ("sched/fair: Do not migrate if the prev_cpu is idle") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: fsmark on test machine: 4 threads Intel(R) Core(TM) i5-2300 CPU @ 2.80GHz with 4G memory with following parameters: iterations: 1x nr_threads: 32t disk: 1HDD fs: ext4 filesize: 16MB test_size: 60G sync_method: fsyncBeforeClose nr_directories: 16d nr_files_per_directory: 256fpd cpufreq_governor: performance test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload. test-url: https://sourceforge.net/projects/fsmark/ Details are as below: --------------------------------------------------------------------------------------------------> To reproduce: git clone https://github.com/intel/lkp-tests.git cd lkp-tests bin/lkp install
