[fs] a0918006f9: netperf.Throughput_tps -11.6% regression

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Greeting,

FYI, we noticed a -11.6% regression of netperf.Throughput_tps due to commit:


commit: a0918006f9284b77397ae4f163f055c3e0f987b2 ("[PATCH v15 1/3] fs: Add trusted_for(2) syscall implementation and related sysctl")
url: https://github.com/0day-ci/linux/commits/Micka-l-Sala-n/Add-trusted_for-2-was-O_MAYEXEC/20211013-032533
patch link: https://lore.kernel.org/kernel-hardening/20211012192410.2356090-2-mic@xxxxxxxxxxx

in testcase: netperf
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:

	ip: ipv4
	runtime: 300s
	nr_threads: 16
	cluster: cs-localhost
	test: TCP_CRR
	cpufreq_governor: performance
	ucode: 0x5003006

test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/


please be noted we made out some further analysis/tests, as Fengwei mentioned:
==============================================================================
Here is my investigation result of this regression:

If I add patch to make sure the kernel function address and data address is
almost same even with this patch, there is almost no performance delta(0.1%)
w/o the patch.

And if I only make sure function address same w/o the patch, the performance
delta is about 5.1%.

So suppose this regression is triggered by different function and data address.
We don't know why the different address could bring such kind of regression yet
===============================================================================


we also tested on other platforms.
on a Cooper Lake (Intel(R) Xeon(R) Gold 5318H CPU @ 2.50GHz with 128G memory),
we also observed regression but the gap is smaller:

Fengwei also helped review these results and commented:
I suppose these three CPUs have different cache policy. It also could be
related with netperf throughput testing.

Details are as below:
-------------------------------------------------------------------------------------------------->


To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
