Doesn't load average count the average number of processes waiting on (or in) a 'run' state? Don't the ipfw functions get performed by the kernel? If so, wouldn't the only rise in load average be from a secondary effect on 'coalmine canary' like programs? If you aren't running apache or lotsa sendmail or something would loadave even go up much under heavy load?
