This is not true in Nessus 3 (preferably 3.0.2) : (or less true,
depending on how you see it)

Basically, in Nessus 3 you can account for ~ 6megs of ram per scanned
host in parallel (plus a fixed amount of ram of ~ 30Megs for the
master process). CPU usage has also been reduced extensively. Meaning
that if you have 1gig of ram on your system, you can/could (depending
on your bandwidth) scan between 100 and 120 hosts in parallel and
still have some room for other programs to run.
What is slow is the initial processing of the plugins, but that
happens only once per update.
