Subject: [perf] 06e0dbcfd3: phoronix-test-suite.mbw.0.mib_s 12.6%
improvement
Greeting,
FYI, we noticed a 12.6% improvement of phoronix-test-suite.mbw.0.mib_s due to commit:
commit: 06e0dbcfd33c53ac0046e5a1f93f7b8d71c40fc7 ("[PATCH 2/3] perf: Optimize perf_init_event()")
url: https://github.com/0day-ci/linux/commits/Peter-Zijlstra/Various-optimizations-for-event-creation/20191024-170638
in testcase: phoronix-test-suite
on test machine: 16 threads Intel(R) Xeon(R) CPU X5570 @ 2.93GHz with 48G memory
with following parameters:
test: mbw-1.0.0
cpufreq_governor: performance
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.
