[dpdk-dev] About round trip latency with DPDK

[Wodkowski, PawelX]

Refer to DPDK getting started guide paragraph 5.4. It might help.
Also it might be easier to do write simple application that send a packet on port 1 and rx it on port 2 in separate threads on separate cores (simple physical loop). You can then add timestamp and send packet back and see how long it will take TX to RX and RX to TX process.
