I note your speed is pretty low compared to my chart listing,

Not sure...I noticed the speed as well. I had raised the conf parameter:
From: netusage 1600 Kbps
To: netusage 7200 Kbps
I can't recall if that's bits or bytes (small b should be bits, right?).
But I'll try raising it alot more, since all dumps are over 100mbit
ethernet.
That parameter is only a guide to amanda. If amanda sees that the current
backups coming over the network are using more than 'netusage' bandwidth,
it won't start another one. But it doesn't throttle running backups to
fit within netusage.
Besides that, amtapetype only showed the slow speed. That means the cause
has to be your tape drive, tapes, or the SCSI chain the tape drive is on.
Those are the only things involved in running amtapetype.
