Hi all,
I'm using dpdk 1.8 and pktgen-dpdk 2.8 to generate traffic on a back-to-back
setup both equipped with 82599EB 10-Gigabit NIC.
The problem is when I start it, pktgen indicates 10000Mbits/s Tx with 64B
packet size, but I'm receiving about 15% of it on the other end.
This percentage seems to be proportional with the packet size.
e.g.
Using nload to read Rx traffic
Pktgen: Tx: 10000Mbits/s ==> Other end: Rx 1660 Mbits/s
Rate: 100%
Pkt size: 64B
e.g 2
Pktgen: Tx: 10000Mbits/s ==> Other end: Rx 9385 Mbits/s
Rate: 100%
Pkt size: 1518B
Pktgen is started with this command on a Xeon(R) CPU E31270 @ 3.40GHz
./app/pktgen -c 1f -n 3 --proc-type auto --socket-mem 1024 --file-prefix pg --
-p 0x3 -P -N -m "[1:3].0, [2:4].1"
Is there something I'm not configuring correctly or something I have miss?
Also, the % rate is acting strangely since anything above 50% doesn't change
the Tx rate and anything below is modifying it
e.g Tx: 10000Mbits/s 5000Mbits/s
%Rate: >=50% 25%
Thanks
Alexandre F.
