Basically, the SHA256 checksum code within ZFS looks like it could use a little helping hand. On my limited testing, it would appear that Solaris 11 has at least a 20-25% edge in efficiency when doing SHA256 checksumming for ZFS. IANAP, but it would be extremely nice to be able to have the same (or better) efficiency for ZFS on FreeBSD. I have not done specific testing with Fletcher4, but that also seemed to be slightly better tuned in Solaris 11 as well. >How-To-Repeat:
