 Thank you very much for following up on this.  Any further optimization of =
 checksums is gravy, for everyone that uses FreeBSD/ZFS.  Sure Fletcher4 is =
 pretty light, but every little bit helps.  Fewer CPU cycles used =3D less l=
 atency =3D more win.  I think for crypto/dedup applications, perhaps effort=
  should be focused on an optimized implementation of Keccak (SHA3 winner) i=
 nstead of SHA256?
