i came across a text file benchmark i did with the 2nd latest cryptsetup
and thought id see how 1.6.3 would look
i have different kernel and libgcrpyt versions since 1.6.2 as well and
it was said on the gnupg list when libgcrypt 1.6.0 came out there were
some speed improvements
what would likely be the main source of speed increases - kernel or
libgcrypt ?
serpent decryption is vastly faster, twofish in general but seems AES isn't
$ cryptsetup benchmark
1.6.2
libgcrypt 1.5.3
