Found the program. Under RELENG_4, its quite happy doing
cryptotest -t 4 -p -a aes 100000
92.781 sec, 200000 aes crypts, 16 bytes, 34490
byte/sec, 0.3 Mb/sec
dispatch->invoke: avg 3599 ns : min 1955 ns : max 55315 ns [800048 samps]
invoke->done: avg 56574 ns : min 32406 ns : max 158121 ns [800048
samps]
done->cb: avg 3707 ns : min 1677 ns : max 57270 ns [800048

cb->finis: avg 5286 ns : min 2235 ns : max 63695 ns [800048

not a HiFn specific thing.
