[one-users] question about OpenNebula + NFS performance

[Nikolay Gar]

nfsstat from client and nfs server will help:

1. nfsstat -n -c for client
2. nfsstat -n -s for server

Just for test, do not test it on VM machine , simple copy some file over
NFS ( some big file not /dev/null some 5 GB) with time command before test
