Hi Olivier,
Can you perhaps also include the specific testpmd parameter you used in your tests, as they can have a large effect on performance. On my Sandy Bridge platform here are the testpmd flags I use for iofwd testing:
"--rxd=128 --rxfreet=32 --rxpt=8 --rxht=8 --rxwt=0 --txd=512 --txfreet=32 --txpt=32 --txht=0 --txwt=0 --txrst=32 --txqflags=0xF01 --numa --burst=32 --mbcache=250 --total-num-mbufs=16383"
Regards,
