Alan,

Most people report faster throughput without nfs, your result is weird.
Your sample is small (1.5GB), is it possible it was cached by the nfs client? 
Do amanda and NFS use the same network route?
Do the NFS server have enough memory and cpu to run the amanda client software? 
Check the network cards, do they report error?

Just one dle.
No compression - data is already compressed (gzip).
No encryption.
I am using holding disk.

Attached files: -

amdump.1 direct from client
amdump.3 through NFS.
