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
