Hi shiane and all
Emre and Stephen, thanks your suggest for us.
We are not testing multi-port traffic gen using NETMAP though DPDK l3fw,
but we understood some packet recive-side without NETMAP Linux.
Please try it using stephen's pktgen if you have more traffic gen/recive
server resources or Us
Actually, I made my own packet reception application using DPDK
to utilize multiple RSS which map each core (in my case, 12 queues for 12
cores).
But it shows that multiple RSS shows, the reception performance is rather
decreasing as below.

Thanks for sharing Naoto.
So in your experiments, the forwarding performance still does not reach the
line rate.
Your perf record shows that the cpu spend most of the time in polling for
receiving packets,
and no other heavy operation.
Even though the application polling packets in its best,

Hello, all.
I play the dpdk-1.2.3r1 with examples.
But I can not achieve the line-rate packet receive performance,
and the performance is not scale with multiple ports.
For example, in example l2fwd, I have tested two cases with 2 ports, and 4
ports,
using belowed command line each
./build/l2fw

Hello Shinae,
Did you try to use the testpmd tool with multiple queues per port? It
gives you more flexibility compared to l2fwd app.
You need to trigger the RSS feature of the NIC by sending different
streams (just by changing the destination port for instance or any
