Are you using T2000 servers? This blog entry helped us improve
performance, though I don't think we were even that slow in the
beginning.

Subject: Re: [Veritas-bu] SSO slower than network issue

By putting SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS in
/usr/openv/netbackup/db/config i have managed to increase the speed to ~
11-13MB/s but thats more like 100Mbit network connection speeds and not
throughput you'd expect over a 2GB HBA.

We have another media server same setup which gets like 35MBs.

Anyone any tips?

Cheers
