Subject: [linus:master] [mm] 12214eba19: vm-scalability.throughput 49.5% improvement
Date: Wed, 15 Nov 2023 22:01:44 +0800 [thread overview]
Message-ID: <202311151633.ee9bb41f-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a 49.5% improvement of vm-scalability.throughput on:
commit: 12214eba1992642eee5813a9cc9f626e5b2d1815 ("mm: handle read faults under the VMA lock")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: vm-scalability
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:
runtime: 300s
size: 2T
test: shm-pread-seq
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
