Hi James,

I had the same problem on a windows NT platform. My machine has a dual pentium 
200 with 128MB of mem and had two SCSI controllers one mylex RAID and a dual 
adaptec ultra SCSI controller. The Mylex RAID had a mirrored system disk and a 
RAID five data disk.The network connection is a 100MHZ ethernet connection via 
a network switch.  I installed ADSM on the RAID five (9GB)  including a 5GB 
backuppool. The backup didn't perform to my expectation. Tuning of ADSM didn't 
make much difference. I installed a SCSI to SCSI RAID controller and moved the 
log ,DB and the backup pool to the much faster RAID system. 
Our initial throughput was around the 1.5MB per hour.
after the new RAID on a seperate controller we where getting 5 to 7GB an hour 
for each session.
You may have the same problem.
Also look at the client book re large restore and the command line backup to 
increase performance.

from the windows client book

3.17 Performing Large Restore Operations
 
With Windows NT, if you need to restore a large number of files, you will get 
faster performance using the 
command-line interface rather than the GUI.  In addition, you will improve 
performance if you enter multiple 
restore commands at one time. For example, to restore all the files in your c: 
file space, you would enter:
 
     dsmc restore c:\*.* -subdir=yes -replace=all -tapeprompt=no
 
However, if you enter multiple commands for the root directories in your c: 
file space, ADSM can restore 
the files faster. For example, you would enter these commands:
 
     dsmc restore c:\users\ -subdir=yes -replace=all -tapeprompt=no
     dsmc restore c:\data1\ -subdir=yes -replace=all      dsmc restore 
c:\data1\ -subdir=yes -replace=all -tapeprompt=no
     dsmc restore c:\data2\ -subdir=yes -replace=all      dsmc restore 
c:\data2\ -subdir=yes -replace=all -tapeprompt=no
 
 
Or, if you need to restore files for multiple drives, you would enter these 
commands:
 
     dsmc restore c:\*.* -subdir=yes -replace=all -tapeprompt=no
     dsmc restore d:\*.* -subdir=yes -replace=all -tapeprompt=no
     dsmc restore e:\*.* -subdir=yes -replace=all -tapeprompt=no
 
You can also use the quiet option with the restore command to save more 
processing time. However, 
you will not receive informational messages for individual files.
 
Note:  If you already have the appropriate values set for the subdir, replace, 
tapeprompt, and quiet 
       options in your client options file, it is not necessary to include 
these options in the commands.
