[mm] 6471384af2: hackbench.throughput -4.9% regression
by kernel test robot
Greeting,
FYI, we noticed a -4.9% regression of hackbench.throughput due to commit:
commit: 6471384af2a6530696fc0203bafe4de41a23c9ef ("mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
nr_threads: 100%
mode: process
ipc: socket
cpufreq_governor: performance
ucode: 0xb8
test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler.
test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sc...
In addition to that, the commit also has significant impact on the following tests:

[net] 19f92a030c: apachebench.requests_per_second -37.9% regression
by kernel test robot
Greeting,
FYI, we noticed a -37.9% regression of apachebench.requests_per_second due to commit:
commit: 19f92a030ca6d772ab44b22ee6a01378a8cb32d4 ("net: increase SOMAXCONN to 4096")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: apachebench
on test machine: 16 threads Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz with 48G memory
with following parameters:
runtime: 300s
concurrency: 4000
cluster: cs-localhost
cpufreq_governor: performance
ucode: 0x7000019
test-description: apachebench is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server.
test-url: https://httpd.apache.org/docs/2.4/programs/ab.html
In addition to that, the commit also has significant impact on the following tests:
+------------------+------------------------------------------------------------------+

Setup of that test is trying different file system types, and it looks
at errno code of "mount -t $fs /dev/zero /mnt/$fs".
Test still PASSes. This report appears to be only about extra message in dmesg,
which wasn't there before:
# mount -t xfs /dev/zero /mnt/xfs
# dmesg -c
[ 897.177168] /dev/zero: Can't open blockdev

[cpuidle] 331b89c842: unixbench.score 5.6% improvement
by kernel test robot
Greeting,
FYI, we noticed a 5.6% improvement of unixbench.score due to commit:
commit: 331b89c8420810efbf395f3bba69b075b56a4c11 ("cpuidle: Use nanoseconds as the unit of time")
https://github.com/0day-ci/linux UPDATE-20191109-152231/Rafael-J-Wysocki/cpuidle-Use-nanoseconds-as-the-unit-of-time/20191109-002344
in testcase: unixbench
on test machine: 160 threads Intel(R) Xeon(R) CPU E7-8890 v4 @ 2.20GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 1
test: shell8
cpufreq_governor: performance
ucode: 0xb000038
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
