On AltiVec (4xOMP):

[before]
pbkdf2-sha1:	35840 c/s real, 8982 c/s virtual
pbkdf2-sha256:	14194 c/s real, 3566 c/s virtual
pbkdf2-sha512:	5944 c/s real, 1489 c/s virtual

[after]
pbkdf2-sha1:	36141 c/s real, 9057 c/s virtual
pbkdf2-sha256:	14336 c/s real, 3592 c/s virtual
pbkdf2-sha512:	5936 c/s real, 1498 c/s virtual


On NEON (2xOMP):

[before]
pbkdf2-sha1:	578 c/s real, 289 c/s virtual
pbkdf2-sha256:	276 c/s real, 138 c/s virtual
pbkdf2-sha512:	125 c/s real, 62.7 c/s virtual

[after]
pbkdf2-sha1:	501 c/s real, 250 c/s virtual
pbkdf2-sha256:	276 c/s real, 138 c/s virtual
pbkdf2-sha512:	125 c/s real, 62.7 c/s virtual


There's no significant change on Altivec, while SHA1 somehow gets slower on NEON.
