Do you have any pointer to help on benchmarking the network, perhaps a 
checklist or some scripts for netperf ?

There are some scripts in doc/examples but they are probably a bit long 
in the tooth by now.

The main writeup _I_ have on netperf would be the manual, which was 
recently updated for the 2.4.3 release.

http://www.netperf.org/svn/netperf2/tags/netperf-2.4.3/doc/netperf.html

or the current top of trunk:

http://www.netperf.org/svn/netperf2/trunk/doc/netperf.html

There is also a netperf-talk@netperf.org mailing list which one can join 
and have discussions about netperf, and a netperf-dev@netperf.org if one 
wants to discuss actual netperf (netperf2 or netperf4) development.
