I see, it is exactly what you said, thanks.

So to analyze or enhance performance, the value of "avg processing cycles per packet" should be looked to evaluate ovs-dpdk, which gives the result of processsing cycles per packet for a specified pmd, right?

For a given pipeline of matching and actions:
That is one parameter that can be used
Total throughput for a given packet size as measured externally is another.
