Again, please get rid of the localhost before it bites you.  Use the 
FQDN instead.

And those are all figures I wouldn't mind seeing here, but then I only 
have 2 drives, both ata100's.  In any event I sure don't see that as 
the cause of a slowdown.

Give each (non-raid) disk its own spindle number, and give the raids 
their own spindle number.  But thats sure slow on /home.

The only reason I can see is that the slow one is using 'user-tar' 
whereas the speedier ones are using the 'root-tar' dump profiles.

Can you post those 2 dumptypes from your amanda.conf?
