This is probably more appropriate for the cisco-nsp list, but what process is taking up the CPU or is it due to interrupts? To the best of my knowledge the crypto should be hardware accelerated, while everything else is going to be done in software on the 3800.
The ISR series do have onboard hardware crypto, but I don't know offhand if it can handle a full DS3 worth. My first guess is fragment reassembly would probably kill it fast. ~Seth
