AFAIK, bonding can not give increased bandwidth between two hosts - the maximum you can ever get is the bandwidth of one of the links i.e. if you have a server with say 4 bonded interfaces, any one client can only get a maximum bandwidth of one of the interfaces on the server. I've used 2 bonded (mode 6) Gigabit interfaces on NFS servers and can get 200+Mbyte/s read speeds using multiple clients James Pearson
