Subject: [btrfs] d5178578bc: fsmark.files_per_sec 54.4% improvement
Greeting,
FYI, we noticed a 54.4% improvement of fsmark.files_per_sec due to commit:
commit: d5178578bcd461cc79118c7a139882350fe505aa ("btrfs: directly call into crypto framework for checksumming")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
iterations: 1x
nr_threads: 1t
disk: 1BRD_48G
fs: btrfs
filesize: 4M
test_size: 24G
sync_method: fsyncBeforeClose
ucode: 0x400001c
cpufreq_governor: performance
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
bin/lkp install job.yaml # job file is attached in this email
