gabriel.thomas Aug 11, 2015 1:15 PM (in response to Leo_Yeh)Hello Leo,
Welcome back to the Intel Embedded Community.
We have notice that you are using these addresses: 192.168.0.1/24 and 192.168.1.1/24, according to these IPs you are using different subnets.
Is there any device in between? any router?
Please send a network diagram.
Regards,
Gabriel Thomas

Leo_Yeh Aug 24, 2015 3:03 AM (in response to Leo_Yeh)Hi all,
I have a question again.
why does the performance seems not good?
I mean, port 0/1 are fine.
However, port 2/3 and 4/5, their performance seems bad, maybe 50~60 % only. (MBits/s Rx/Tx)
My 'page cpu' is:
How can I tune the performance ?
Any ideas?
BTW, my OS is ubuntu 14.04
NIC is 82599.
Thanks a lot.
Best regards,
Leo,

That shows the performance you are observing is - it is not CPU bound.
Since it was I/o bound, the more you added, it scaled with I/o.
And with 128 byte packet size you should get what you are looking for.
