Subject: [block] 70bed0d544: fsmark.files_per_sec 92.0% improvement
Greeting,
FYI, we noticed a 92.0% improvement of fsmark.files_per_sec due to commit:
commit: 70bed0d5447e08702c7595d26c88ca37e8eb88b4 ("block: add a bdev_write_cache helper")
git://git.infradead.org/users/hch/block.git block-api
in testcase: fsmark
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
iterations: 1x
nr_threads: 1t
disk: 1HDD
fs: btrfs
fs2: nfsv4
filesize: 4K
test_size: 40M
sync_method: fsyncBeforeClose
nr_files_per_directory: 1fpd
cpufreq_governor: performance
ucode: 0xd000331
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
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.
