That is bad in anybodies book. But you do not say enough about your setup.

Do you use an afs client to do your backup ?

What kind of network are you using (ppp over modems ? :-) How much
load is on the network. What throughput do you get from ping ?

Apart from kByte/sec, what is the number of *files* you get through per
second - If you backup many small files, the network overhead for each 
open could be extremely high, and is impervious to twiddling the chunk
size, or placing the disk cache onto a RAM disk.
