[mm/filemap.c] 06c0444290: stress-ng.sendfile.ops_per_sec 26.7% improvement
by kernel test robot
Greeting,
FYI, we noticed a 26.7% improvement of stress-ng.sendfile.ops_per_sec due to commit:
commit: 06c0444290cecf04c89c62e6d448b8461507d247 ("mm/filemap.c: generic_file_buffered_read() now uses find_get_pages_contig")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 30s
class: pipe
cpufreq_governor: performance
ucode: 0x5003003
Details are as below:

[mm] 4df910620b: will-it-scale.per_process_ops 37.7% improvement
by kernel test robot
Greeting,
FYI, we noticed a 37.7% improvement of will-it-scale.per_process_ops due to commit:
commit: 4df910620bebb5cfe234af16ac8f6474b60215fd ("mm: memcg: relayout structure mem_cgroup to avoid cache interference")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 144 threads Intel(R) Xeon(R) CPU E7-8890 v3 @ 2.50GHz with 512G memory
with following parameters:
nr_task: 50%
mode: process
test: page_fault2
cpufreq_governor: performance
ucode: 0x16
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

[locking/qspinlock] 0e8d8f4f12: fsmark.files_per_sec 213.9% improvement
by kernel test robot
Greeting,
FYI, we noticed a 213.9% improvement of fsmark.files_per_sec due to commit:
commit: 0e8d8f4f1214cfbac219d6917b5f6460f818bb7c ("[PATCH v13 3/6] locking/qspinlock: Introduce CNA into the slow path of qspinlock")
url: https://github.com/0day-ci/linux/commits/Alex-Kogan/Add-NUMA-awareness-to...
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git cb262935a166bdef0ccfe6e2adffa00c0f2d038a
in testcase: fsmark
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
iterations: 1x
nr_threads: 64t
disk: 1BRD_48G
fs: btrfs
filesize: 4M
test_size: 24G
sync_method: NoSync
cpufreq_governor: performance
ucode: 0x5003003
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:
