Thanks for the info. Indeed I meant packet size. Funny that you mention
cpu utilization. I found myself bickering with our Cisco reseller over the
difference in cpu load between DES and 3DES. He said there was no
difference and I saw (somewhere) on CCO that it was nearly 50% more
processor intensive on a PIX using 3DES than on (ordinary) DES.

What do you mean by payload? I assume you mean packet size. I don't have
the exact figures but I the overhead on packet size is about 10%. The
overhead on the CPU utilization could be 100%, which might be what he is
thinking of.
