Did you configure the bonding like it should be? Cause configuring a 
loadbalanced bonding (which I suppose you're using) is not at all an easy 

For example if you are using rr bonding the switch where the nfsserver is 
connected to has to channel the ports the nfs-server is connected to. And 
much more.

I would recheck bonding. Test how fast it is with only one nic in the bond and 
the like. But first of all read the bonding.txt which comes along with the 
kernel-docs or can be found here:
