Subject: [LKP] [Btrfs] e329073364: blogbench.write_score 84.7% improvement
Greeting,
FYI, we noticed a 84.7% improvement of blogbench.write_score due to commit:
commit: e329073364273aa260af9a62e4074796685abafd ("Btrfs: kill btrfs_clear_path_blocking")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: blogbench
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
disk: 1SSD
fs: btrfs
ucode: 0xb00002e
cpufreq_governor: performance
test-description: Blogbench is a portable filesystem benchmark that tries to reproduce the load of a real-world busy file server.
test-url: https://www.pureftpd.org/project/blogbench
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
