 I'll gather some numbers together comparing OmniOS (Illumos) vs FreeBSD and=
  get back some numbers for you.  I can use my Xeon E3-1240 at home for the =
 benchmarking, it'll just take me some time to gather everything together to=
  do it.  Are there any specific tools you'd like me to run, or just basic z=
 pool iostat and mpstat / top -P ?

 Actually after double checking it looks like FreeBSD doesn't use the same S=
 HA-256 implementation in ZFS as illumos so there may well be something to l=
 ook at there.
 
 Would be good to know the difference in performance between FreeBSD and Ope=
 nindiana (illumos distribution).
