What do you have set as your port range. When I select to scan all ports,
it takes much more time than that. When I have it set to run just the known
ports, its more like 15 minutes.
Also, do you have "Optimize Scan" checked? That will make it so nessus does
not run checks that are not pertainent.

Subject: How long should Nessus take to do a full scan?
Hi there
I'm finding that Nessus-2.2.4 (and previous) on a P-IV takes 30-50 minutes
to do a full scan a single LAN-connected Windows host - including local
Admin access to access the Registry/etc.
Scanning a Linux box with root/password takes a similar amount of time.
There are a lot of tests, but I have set max_checks=15 on both client and
server, so several should be running simultaneously.
Does that sound about right, and if not, any ideas as to what I have set
up incorrectly that could be slowing things down? Nessus certainly looks
busy while it's running (i.e. top shows nessus processes taking the
majority of resources)
