I would try:
backing up to disk first (disk pool)
or backup to multiple tape drives at once. How many tape drives to you have?
collocate by filespace might help (but I'm not sure for P & T)
tune your TSM database (what is your server?)
make multiple volumes on your NetWare server or you could try the virtual mount
point option
make sure your NetWare server has enough CPU and memory
what is LAN connection to your TSM server?
check the RESOURCEUTILIZATION parameter of the client, as well as
TCPBuffersize, TCPWindowSize, TCPNODELAY, TXNBytelimit
check the number of mount points for the node:
tsm: UNXR>q node unxp f=d
Node Name: UNXP
Platform: AIX
Client OS Level: 4.3
Client Version: Version 4, Release 1, Level 3.0
<snip>
Keep Mount Point?: No
Maximum Mount Points Allowed: 6
why don't you use hardware compression? Software (compression) is definitely
not what you want.
You are right about the performance could be better:
Here is AIX Client that is tune well (I hope!):

PS: Does any one else have the Aggregate exceed the Network transfer rate? This
seems odd, but I think that the multiple streams to the server account for the
apparent discrepancy.

I had a Netware 4.1 with TSM Client 4.1.2.16 backing directly on Scalar
1000 (DLT8000). I run a full backup and the process took so long **..

The transfer time and transfer rate looks O.K but look to the Aggregate
data transfer rate !!!!
No compress involve * Any idea how can I improve this process
Thanks in Advance
