    my core i7 e.g. lynnfield doesn't have aes-ni or avx - so I'm grateful that all the x86_64 optimizations exist (CONFIG_CRYPTO_BLOWFISH_X86_64, CONFIG_CRYPTO_CAMELLIA_X86_64, CONFIG_CRYPTO_SERPENT_SSE2_X86_64, CONFIG_CRYPTO_TWOFISH_X86_64, CONFIG_CRYPTO_TWOFISH_X86_64_3WAY)

    will try those patches out - let's see if it cuts down latency on these

    dm-crypt/luks -> lvm -> filesystem layouts


    ok seems like it's still heavily worked on, debated

    so will try it a later time
