[Ndn-interest] Regarding RTT for ndncatchunks in raspberry pi

I'm a student working on a testbed of NDN. The testbed consists of four
raspberry pi connected in a bus topology. The two end devices act as
producers and consumers for NDN data. The middle two devices act as
routers. I use ndncatchunks to send a 100 MB file through the testbed. I
observe that the RTT for this is significantly more (around 10 times more)
than that for an FTP application on the same testbed. The throughput is
also lesser compared to FTP (around 20% lesser for NDN). I was wondering
what could cause this difference.
Also, another observation I made was that when I was testing the testbed
setup with ndnping, the RTT was not so high.
I have also previously worked on similar topology with NDN and the machines
used were desktop machines. In this case, NDN was better than FTP.
Any thoughts on what could be causing this?
Thanks and Regards
