Subject: [tcp] 01b4c2aab8: lmbench3.TCP.socket.bandwidth.10MB.MB/sec -20.2%
regression
Greeting,
FYI, we noticed a -20.2% regression of lmbench3.TCP.socket.bandwidth.10MB.MB/sec due to commit:
commit: 01b4c2aab841d7ed9c5457371785070b2e0b53b1 ("[PATCH v3 net-next 3/3] tcp: add one skb cache for rx")
url: https://github.com/0day-ci/linux/commits/Eric-Dumazet/tcp-add-rx-tx-cache-to-reduce-lock-contention/20190323-091742
in testcase: lmbench3
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
test_memory_size: 50%
nr_threads: 100%
mode: development
test: TCP
cpufreq_governor: performance
ucode: 0xb00002e
test-url: http://www.bitmover.com/lmbench/
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
