Good news if you have an ipsec tunnel or an encrypted rootfs: while
linux-3.2 carries an SSSE3 based SHA1 implementation for x86-64 (up to
2.3x faster), linux-3.3 will have an x86_64/SSE2 optimized Serpent
cipher algorithm. I tried it in my laptop's encrypted rootfs
(Serpent/SHA256) and it's 3x times faster!
