[writeback] e4f9eb2268: fsmark.files_per_sec 48.8% improvement

by kernel test robot

Greeting, FYI, we noticed a 48.8% improvement of fsmark.files_per_sec due to commit: commit: e4f9eb2268da0eb6b706fe582ef34cbfc359c799 ("[RFC v3] writeback: add elastic bdi in cgwb bdp") url: https://github.com/0day-ci/linux/commits/Hillf-Danton/writeback-add-elast... in testcase: fsmark on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory with following parameters: iterations: 1x nr_threads: 32t disk: 1HDD fs: f2fs filesize: 16MB test_size: 60G sync_method: NoSync nr_directories: 16d nr_files_per_directory: 256fpd cpufreq_governor: performance ucode: 0x500002b 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/ In addition to that, the commit also has significant impact on the following tests: +------------------+----------------------------------------------------------------------+ | testcase: change |

[mm/swap] f7234972f2: will-it-scale.per_process_ops -2.3% regression

by kernel test robot

Greeting, FYI, we noticed a -2.3% regression of will-it-scale.per_process_ops due to commit: commit: f7234972f27a33730cf1b5bc6a4c486021a35601 ("mm/swap: Add static key dependent pagevec locking") https://git.kernel.org/cgit/linux/kernel/git/bigeasy/staging.git mm_swap in testcase: will-it-scale on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory with following parameters: nr_task: 50% mode: process test: brk1 cpufreq_governor: performance ucode: 0x500002b test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two. test-url: https://github.com/antonblanchard/will-it-scale If you fix the issue, kindly add following
