I want to share with you information about TSM performance, using an AS/400
as a TSM server.  What I discovered is that performance is NOT tied to the
network speed, NOT tied to the tape drive speed, BUT to the files size and
to the client performance.  I did not use client compression as I verified
that this feature punishes overall performance.
I saw a 4 GB/hour speed, with files whose average size was about 3 MB each.
For bigger files, better performance.

Saludos / Regards / Au revoir
