Subject: [SUNRPC] 0472e47660: fsmark.app_overhead 16.0% regression
Greeting,
FYI, we noticed a 16.0% improvement of fsmark.app_overhead due to commit:
commit: 0472e476604998c127f3c80d291113e77c5676ac ("SUNRPC: Convert socket page send code to use iov_iter()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
iterations: 1x
nr_threads: 64t
disk: 1BRD_48G
fs: xfs
fs2: nfsv4
filesize: 4M
test_size: 40G
sync_method: fsyncBeforeClose
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
bin/lkp run job.yaml
