here is some info :

We have performance problem with a 47 GB partition (on the backup server).
OS : Linux Redhat Enterprise AS 3 V4
Version : amanda-2.4.4p1

/dev/cciss/c1d0p2     160G   56G   97G  37% /amanda

inparallel 50

50 dumpers!! and amplot shows only a few active.  Probably overkill.

netusage  30000
maxdumps 5

So you do allow 5 dumps on the same host?
Only do this when having set the correct "splindle" for each DLE,
otherwise you're garuanteed to step on your toes by trashing
the disk, resulting in an even slower estimate/backup.

holdingdisk hd1 {
    comment "main holding disk"
    directory "/amanda/daily"
    use -50 Mb
    chunksize 4 Gb
(...)
}

Can force the backup order so this partition is the first one to be backup ?

In amanda.conf add:

dumperorder "T..."
# fill the dots with other letters, as many
# as you have "inparallel" (best set them to a reasonablenumber like 8)
# See man page for possible letters to choose
# I have: "TTTTTTTT" in my config
