Subject: [cpuidle] 331b89c842: unixbench.score 5.6% improvement
Greeting,
FYI, we noticed a 5.6% improvement of unixbench.score due to commit:
commit: 331b89c8420810efbf395f3bba69b075b56a4c11 ("cpuidle: Use nanoseconds as the unit of time")
https://github.com/0day-ci/linux UPDATE-20191109-152231/Rafael-J-Wysocki/cpuidle-Use-nanoseconds-as-the-unit-of-time/20191109-002344
in testcase: unixbench
on test machine: 160 threads Intel(R) Xeon(R) CPU E7-8890 v4 @ 2.20GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 1
test: shell8
cpufreq_governor: performance
ucode: 0xb000038
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
