bismark, please check your motherboard bios version and the kernel
version.
there are a few known issues with apic irq polling using one logical
hyperthreaded CPU versus all for some AMD boards with NVIDIA chipsets.
Please post your MB chip-set and kernel information.
We are both running on Lenovo T60p laptops, 2 GHz Core 2 Duo' /w ATI video
chipset. So no issue with AMD and/or Nvidia chipsets.

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.
