Hi,
I've checked it further, based on Stephen's suggestion I've tried perf

I've also started to strip down miniflow_

Hi,
I've set up a simple packet forwarding perf test on a dual-port 10G
82599ES: one port receives 64 byte UDP packets, the other sends it out,
one core used. I've used latest OVS with DPDK 2.1, and the first result
was only 13.2 Mpps, which was a bit far from the 13.9 I've seen last

Use perf top it gives much better data than oprofile
