Subject: [hwrng] a583ed310b: netperf.Throughput_total_tps 9.7% improvement
Greeting,
FYI, we noticed a 9.7% improvement of netperf.Throughput_total_tps due to commit:
commit: a583ed310bb6b514e717c11a30b5a7bc3a65d1b1 ("hwrng: cctrng - introduce Arm CryptoCell driver")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: netperf
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 16
cluster: cs-localhost
test: TCP_CRR
cpufreq_governor: performance
ucode: 0x2000065
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
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
