Subject: [locking/qspinlock] 0e8d8f4f12: fsmark.files_per_sec 213.9%
improvement
Greeting,
FYI, we noticed a 213.9% improvement of fsmark.files_per_sec due to commit:
commit: 0e8d8f4f1214cfbac219d6917b5f6460f818bb7c ("[PATCH v13 3/6] locking/qspinlock: Introduce CNA into the slow path of qspinlock")
url: https://github.com/0day-ci/linux/commits/Alex-Kogan/Add-NUMA-awareness-to-qspinlock/20201223-135025
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git cb262935a166bdef0ccfe6e2adffa00c0f2d038a
in testcase: fsmark
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
iterations: 1x
nr_threads: 64t
