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.
