Key setup times are not that important in a key agile system like
ipsec.
Most crypto libraries let you save your set up key in a data structure
and pass that data structure to the encrypt/decrypt functions. Once
you've set up the keys once, even if you have to change which pre-set
up key you are using at each and every encryption call, it is just a
question of selecting the correct "key context" to pass to the calls.
In summary, key setup time isn't that important for IPSec.
