Re: Client 4.1.3 for Win95 much slower by incremental backups

Rene,

this was discussed here month ago. Read the thread "TSM post upgrade
performance tunning" and the answer of Walter Ridderhof.
I think this should help. Thank you Walter.

Subject:        Client 4.1.3 for Win95 much slower by incremental backups

Hi,

our laptop users begin to call us after upgrading the TSM client from
3.1.0.8 to 4.1.3 (Win95). Our server is 4.1.4 (OS/390).

Since the upgrade, incremental backups take 5 times longer (see below). Why
??

The aggregate data transfer rate went down a lot, thanks for any tips
