  i have a vpn1401, and 'openssl speed' doesn't seem to cause
  any use on the hifn ( per watching 'systat vmstat' )

  to see the hifn in use, i can try something like:
 
$ sudo sysctl -w kern.usercrypto=1
kern.usercrypto: 0 -> 1
$ time openssl enc -des3 -in sengoku.mpg -k none -out /dev/null
    22.04s real     0.16s user     0.50s system
( the hifn is making many ~350 interrupts/second at that time )

then if i turn kern.usercrypto to 0, 

$ time openssl enc -des3 -in sengoku.mpg -k none -out /dev/null
   18.41s real     9.59s user     0.20s system

  so you can see the 'user' has gone up quite a bit.

  the machine is a pIII/450, so slighly beats the hifn in this
  process, but that's not the point.

  if there is a way to make 'openssl speed' actually test the
  hifn, i'd love to hear it -- or if i just must have something
  setup wrong...
