[Nfd-dev] [EXT] ndnping RTT vs. ping RTT

[Junxiao Shi]

Hi Ishita

This is expected behavior. IP stack is implemented in kernel and highly
efficient. NDN stack is implemented in userspace, which has additional
overhead: buffer copying, context switching, etc. Thus, ndnping would have
higher latency.

Yours, Junxiao
