To me, the bigger issue is what hardware you are running the OS on.
I have a laptop with an old Pentium 150 MMX processor and 80 MB of RAM that runs Debian Linux 3.0. I have run nessusd on it before. The system would quickly use up all of its available resources and become quite slow if I tried to scan more than a few systems at a time.
I now have nessusd running under Debian Linux 3.0 on a IBM PC with a PII 300 and 128 MB of RAM and it runs like a champ.
