Hello,
kernel test robot noticed a 129.0% improvement of stress-ng.iomix.ops_per_sec on:
commit: 50b21d7a066f9a702b1d54ca11fc577302e875cb ("btrfs: submit a writeback bio per extent_buffer")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.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: 10%
disk: 1HDD
testtime: 60s
fs: btrfs
class: filesystem
test: iomix
cpufreq_governor: performance
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
