The client code was enhanced in v5.x to address restore performance issues; 
check the TSM Technical Guide for info, and do upgrade your client...

Subject: Backupset slow restore


I'm experimenting with backupsets.  My first restore from one is going
very slowly.  Not sure why.  Any help would be appreciated, since I would
like to implement this feature on our production TSM system.

Test TSM System:

Server: TSM 5.1.6.5 on AIX 4.3.3 ML 8; 1-CPU F50, 1.25 GB RAM

Client: TSM 4.1.3.0 on Windows NT 4.0 SP6a; Pentium-II @ 350 MHz, 192 MB
Client will be upgraded to ITSM 5.1.x.x as part of the testing.

Backup performance from client to server on the order of 8 MB/s.

Backupset was generated on the server onto two FILE volumes, MaxSized at
250 MB.  Using command line client to restore part of the backupset
("C:\program files") to new location on local C: drive.  Restore
throughput measured via AIX topas is about 100 KB/s. Running time of
restore seems to confirm that performance.

Is this normal?  Is there something about this test that is queering the
performance?

Thanks.
