LAN ThroughPut line rate too low

Hi All,

We have a problem is ethernet line rate too low under throughput test.
For HW measure, the test result of 2 port are pass, we tested SI, insertion lose, return lose and iperf passed.
The picture is iperf test result.

However, we tested throughput from frame size of 66 to 1518 by IXIA, it shows the performance lower than other platform (X86 platform).

You can see that when test 256 packet, Other platform line rate can up to 100%, but NX only has 18%.

Our throughput test machine is iXia XGS12.

BTW, we have another LAN port from I210 as below architecture, this port also has lower line rate problem.

Do you have any sugggestion on it? Or Could you provide any LAN line rate performance test result for reference?
We would like to do a comparison with our data.

Thanks,
Allison

Make sure you are setting to performance mode first:
sudo nvpmodel -m 0

Hi,

Is this command adjust this setting as below photo?

We test thtoughput under 15W 6core mode, and also test 15W 2core

Thanks,

The mode 0 nvpmodel should set all cores to max performance and prevent throttling back. There might be something else going on, but by default most performance testing will do poorly unless you start with all cores maxed out.
