.. these are usually load averages for user space processes. The load 
average can at best be an indicator that something is terribly wrong.
You should never trust them.

All major firewall implementations work at kernel level, so these are not 
accounted for with the load level!  If you want to see what the kernel is 
doing go for kernel optimisation tools..
