Chris, Not sure how you configured your amanda server, I have a similar set of boxes (Lotus notes migrated from a pair of e250s to T2000s), with any compression we perform being on the client we don't use a lot of server, other than holding area, network, but not a lot of CPU, just for local drives being backed up (when amanda client==server).
If I recall, netusage will delay start or re-activation of dumpers dumpers when the network bandwidth threshhold has been crossed, it doesn't throttle actively links. You can I think put different DLE into different pools, for instance we have some amanda servers that utilize multiple network interfaces, if we where going to throttle we'd want to make sure each interface had its own pool of DLE (based on IP address of client and how we where routing) and not have a single cap for all network activity.
