[dpdk-users] Measuring packet throughput

hello,
I'm performing an experiment to measure the performance gain of OVS +
DPDK. The goal is to measure the improvements in packet forwarding. My
setup consist in two physical machines (M1 and M2). Each machine have a
network card with two ports. The two machines where configured in the
following way:
Machine M2: I set up OVS+DPDK and I set up the flow to forward packets
from port1 (eth1) to port2 (eth2)
Machine M1: I installed DPDK packet generator to send packets to M2
using eth1.
M1 M2
----------- -------------
| pktgen | eth1 ------------------> eth1 | ovs+ dpdk |
| | | |
| | eth2 <------------------ eth2 | |
----------- -------------
I have set up everything without problem but I don't know how to
reliably measure the packet throughput for a given port. What tool
should I use? At the moment I have just configured pktgen in machine M1
to get port2 (eth2) statistics but I didn't find any way to put the
results in text format and things go so fast that I cannot capture the
right value. I have read articles and reports where they have measured
this same metric I was wondering what tool they have used to measure it.
Thank you in advance for any help.
