I was hit by this when I switched to gigabit.  Took some work with my
network guys & IBM to get all the settings correct.  The performance
difference was incredible.

Hello everybody,
I need some info regarding the performances of a TSM on AIX urgent ,if any
of u could help , because i'm experiencing some problems.
I've installed TSM 5.2 on a AIX box (5.1 64 bits) and left all the default
parameters .
The performances over a Gbit network are poor , backups of 4 GB taking over
35min (5.1.5 AIX client) . There is no load on server , the disk is busy 5%
.
Do u have any  idea what could causing poor performance and what can be done
?
thanks,
Mada
