Have a look at the "system" CPU usage visible with 'top'. This should
show you how much CPU is being used by the kernel itself (which would
include netfilter). You can also see this with 'vmstat'.

I'm not sure if the load average would reflect this... load average is
supposedly a measure of how many processes were waiting in the run queue
over the last 1, 5 and 15 minutes. Whether "processes" includes the
kernel itself, I don't know (I'm inclined to think yes, though).
