    Try

        echo "262144" > /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS

        echo "64"     > /usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS
     
    ... to start with
     
    Then increase NUMBER to 128, test again, then try 256.
     
    Remeber to test backup and restore.  Settings go on media server, no restart required.
