I believe this comparison is flawed. ncclient uses a pure Python
implementation of SSH while the authors used a Python wrapper around
NET-SNMP (a C implementation) to measure SNMP performance. And the
authors state that they used SNMPv2c (no security) and SSH as the
NETCONF transport. (It is also unclear whether all NETCONF
transactions were executed over a single session or multiple
sessions.)

The design of such experiments is not as easy as it may look at first
glance and it is in particular important to use comparable security
algorithms (ideally the same crypto library).
