This depends a lot on your network infrastructure, but there are a few
general recommendations to make. Make sure that auto-negotation is not set
for all your NetWorker clients, and your NetWorker server. Set each
system's network interface card to the specific setting for the network
ports to which each system is connected.

For the NetWare servers, you need to make sure they are on a half duplex
network. For all your servers, make sure there are no anti-virus packages
running during the period that backups are running.

What is the network load on your NetWorker server's ethernet card like
when these machines begin to back up so slowly? You might be saturating
your NetWorker server's NIC.
