Subject: [linux-next:master] [mm] 8f33a2ff30: stress-ng.resched.ops_per_sec -10.3% regression
Date: Fri, 1 Mar 2024 00:01:14 +0800 [thread overview]
Message-ID: <202402292306.8520763a-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a -10.3% regression of stress-ng.resched.ops_per_sec on:
commit: 8f33a2ff307248c3e55a7696f60b3658b28edb57 ("mm: vmalloc: set nr_nodes based on CPUs in a system")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: resched
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.pthread.ops_per_sec 23.0% improvement |
