bigasm is a way for Networker to test the backup of larges files.
 
The first thing you should do is analyze the network usage during the backups 
from not only the networker server point of view but also from the clients 
point of view. No use to have a highway for your datas if your client go on 
bicycle. Do you have setup a dedicated nic for the backup ? Parallelism ? Kind 
of datas (fileservers, databases, ...) ?
 
Kind regards
