The fast-switched packets are switched at the interrupt level and you can see this from the cpu utilization for five seconds 

i.e "CPU utilization for five seconds: 47%/38%; one minute: 52%; five minutes: 48%"

the first value 47% is the precentage the cpu is running at that moment and the other value 38% mean that
out of 47% the 38% is being switched at the interrupt level which is your fast-swtiched traffic. 

That rule apply for all the switching path

30% is spent in IRQ context (switching packets), not in a specific process.

(... and how these numbers have to be read has been asked and answered
A LOT OF TIMES on this list...)
