Have you tried looking at CPU, Ram usage, Load etc etc... Is

CPU flat out? RAM usage is nominal, CPU usage is about
50% on both processors. Right now running a scan I've got some

usage spiking at some point to cause an increase in the load ?
IO load seems to barely go up while a scan is running. This is from
observation of the drive lights, haven't run an iostat though.
The be_nice = yes change in my nessusd.conf file has made a HUGE change
in
responsiveness. Still not anywhere near the FreeBSD setup but at least
I
can run 30/20 hosts/checks and still have my system usable.
I'm glad the be_nice setting helped out.
I was also curious if the FreeBSD system took longer to scan than
your Linux system. It would be interesting to note if the FreeBSD
system was more responsive but also took longer to complete a scan.
As far as we could tell (Mark I eyeball) the FreeBSD system finished
faster. We even disabled the be_nice setting on the FreeBSD laptop and it
still stayed fairly responsive, a little sluggishness but nothing like on
my system.
Another thing when we do a count of the number of nessusd processes
running, mine are significantly less. I'm guessing these has to do with
how Linux and BSD handles threads and wondering if there may be some
tuning options that could be done on Linux for this.
Mind you these are all eyeball measurements, no formal numbers though.
