If I remember corredctly the defined interfaces are only needed if you
are specifying that a given disklist entry is to backed up directly via
an specific interface (I.E. Private backup networks).
When you look at the report do you see any client contention (I'm sure
you do but is it substantial). I had an issue where the holding_area
was on a heavily utilized bus so the throughput was noticably slower.
So I spread the spindles across different buses (sp???)
What kind of traffic are you seeing when you do a netstat -i 5. You can
raise the netusage amount. But you will find that the hardware does all
of the required throttling needed.
