Hello,
I'm using Netbackup with Solaris 9.
We're on a 100Mbps network, and we just upgraded the server
from an Ultra Enterprise 2 to a SunFire V240, and we also
upgraded from NB 5.0 MP2 to NB 5.1MP2.

The problem is that network performances dropped as if we
were still running at 10Mbps, but we upgraded to 100Mbps
a few months ago. When we were at 10 Mbps, backups completed
with rates like from 300KB/s to 600KB/s, when we upgraded to
100Mbps, performances rose to 2000KB/s to 5000KB/s and some-
times more. This was good on the old server with old NB
version, but since the upgraded, performances dropped to
400KB/s to 500KB/s on nearly all Netbackup clients, but
I checked and both the server and clients are running at
100Mbps according to 'ndd' command.

Does anyone have any clue about what's happening, and how
to restore full performances, at least as good as on the
old setup?

Thanks.
Louis-Luc
