I monitored a machine tonight.
This is a self-backup machine running both the server and the fd, still on a sparc 280r.
The avarage throughput is 1Mb/sec, while the network backup of another fd is 4Mb/sec.
While the machine was backing-up itself, I used "top" to see the machine status.
It was 4% of CPU load, with 3% assigned to postgres (I use postgres as the bacula db).
Then there was 0.5% for bacula-sd and 0.5% for bacula-fd.
Maybe I should use some sort of buffering on bacula?

I'm not a developer :( ... unfortunately --> but you need to see where
is the problem (due high CPU usage; low available RAM etc..) to ask for
optimizations.
Furthermore I do not have sparc machines in my setup to give you
comparison data.
