[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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:
