Subject: [lkp] [SUNRPC] 818e8e4109: fsmark.files_per_sec -7.7% regression
FYI, we noticed a -7.7% regression of fsmark.files_per_sec due to commit:
commit 818e8e4109d58cc55c884223a1d93426024d23d8 ("SUNRPC: RPC transport queue must be low latency")
https://github.com/0day-ci/linux Trond-Myklebust/SUNRPC-Small-optimisation-of-client-receive/20160615-035043
in testcase: fsmark
on test machine: ivb44: 48 threads Ivytown Ivy Bridge-EP with 64G memory
with following parameters: cpufreq_governor=performance/disk=1BRD_48G/filesize=4M/fs2=nfsv4/fs=xfs/iterations=1x/nr_threads=64t/sync_method=NoSync/test_size=40G
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
