Subject: [y2038] 412c53a680: will-it-scale.per_process_ops 11.7% improvement
Greeting,
FYI, we noticed a 11.7% improvement of will-it-scale.per_process_ops due to commit:
commit: 412c53a680a97cb1ae2c0ab60230e193bee86387 ("y2038: remove unused time32 interfaces")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
nr_task: 100%
mode: process
test: mmap2
cpufreq_governor: performance
ucode: 0x2000065
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
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------+
| testcase: change | unixbench: unixbench.score 3.8% improvement |
| test machine | 104 threads Skylake with 192G memory |
| test parameters | cpufreq_governor=performance |
| | nr_task=30% |
| | runtime=300s |
| | test=context1 |
| | ucode=0x2000065 |
+------------------+---------------------------------------------+
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
