I run Fedora8 on a laptop which is not very powerful (1.5 GHz Pentium M,
1.5 GB RAM, sluggish disk) and I have to nice Nessus to keep it
perfectly responsive during long scans. I usually launch nessusd
directly with "nice -n ... nessusd -D"
I encountered severe overloads with early 3.1 versions IIRC, but
this was solved by nice *and* improvements in the later 3.1 versions.

I cannot compare with BSD however and I guess that the general
behaviour depends on the nature of the target network.

My scans take a long time because I usually tests machines on slow
WANs with high ping time (often VSAT connections). I have to make sure
that the network is not overloaded so that the normal users' activities
are not disrupted.
This aspect is now the limiting factor for me.

I expect Nessus 3.2 to be much better on this kind of configuration.
