I'm running NBU 5.1 MP5 on a Solaris 10 server. My catalog directory (/usr/openv/netbackup/db)
is about 1.5 GB, but my catalogs take about an hour (56 min. avg.) to back
up to an LTO-2 fibre drive. I'd run into this on Solaris 9 previously, and
the change to tcp_send_hiwat and tcp_recv_hiwat (support doc #273288) took
care of it, but this server already has those at the recommended setting
of 49152.
Does anybody have any suggestions what else I can check?

Thanks much
