Notes

   nfsometer example #1:

Compare cthon on v3, v4 and v4.1 on a Fedora 18 client VM mounting a Fedora 18 server VM:

 nfsometer zero:/export cthon

The same run is then done with tag "10dd", while another client is running in loadgen mode:

(the "loadgen" client)
 nfsometer -n 10 loadgen zero:/export dd_100m_1k

(wait a while, then on original client)
 nfsometer -t 10dd zero:/export cthon
