Yeah, if you are using older servers, that's definitely going to be a problem
a bottleneck on the server itself, moving to a 66mhz slot should help.
You should also do some file transfer OR iperf/netperf tests and see what
the raw throughput is without involving NetBackup.
Some other things to look at:
In: /usr/openv/netbackup
$ cat NET_BUFFER_SZ
1048576
$ cat NET_BUFFER_SZ_REST
1048576
In: /usr/openv/netbackup/db/config
$ cat NUMBER_DATA_BUFFERS
32
$ cat SIZE_DATA_BUFFERS
262144
$ cat NUMBER_DATA_BUFFERS_RESTORE
32
$ cat SIZE_DATA_BUFFERS_DISK
262144
