Subject: [crypto] beeb460cd1: stress-ng.af-alg.ops_per_sec 17454.7%
improvement
Greeting,
FYI, we noticed a 17454.7% improvement of stress-ng.af-alg.ops_per_sec due to commit:
commit: beeb460cd12ac9b91640b484b6a52dcba9d9fc8f ("crypto: algapi - Avoid spurious modprobe on LOADED")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 1s
class: cpu
cpufreq_governor: performance
ucode: 0xb000038
Details are as below:
