Subject: [LKP] [filemap] 48dc11646a: vm-scalability.throughput -9.5%
regression
Greeting,
FYI, we noticed a -9.5% regression of vm-scalability.throughput due to commit:
commit: 48dc11646ad404e441179e9d48cc2139b1de6a24 ("filemap: drop the mmap_sem for all blocking operations")
https://github.com/0day-ci/linux UPDATE-20181214-093104/Josef-Bacik/drop-the-mmap_sem-when-doing-IO-in-the-fault-path/20181214-073658
in testcase: vm-scalability
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
runtime: 300s
test: lru-file-mmap-read-rand
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
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
