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

<http://www.nessus.org/documentation/index.php?doc=nessus3#mem>

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.
