You are talking about the "netusage" parameter in amanda.conf correct?
Since I'm on shakey ground with my understanding of that parameter,
lets make sure you and I have a correct notion of what it affects.
I'm sure someone will correct any errors I make.

It has no effect on the bandwidth used by a dump or connection.
I.e. it is not a throttle or accelerator. It has to do with whether
the dump of a DLE gets started or not. Once it is started the dump
will use any and all the bandwidth it can get.
When amdump has a free dumper I think it checks the current total
net usage, not just amanda's. Then if the usage is below the netusage
value, the dumper is assigned a task. Otherwise the dumper sits idle
and amdump checks again later.
