cryptsetup benchmark of symmetric ciphers on Linux x86_64

Fri, 21 Mar 2014 19:38:54 +0100
Intel i7-3770
QEMU: 1.7.0 (KVM)
Host / Guest kernel: v3.14-rc5 / v3.14-rc7-59-g08edb33
Trials: 3

Tested implementations: generic, x86_64 optimized, x86_64/SSE2, AES-NI,
x86_64/3-way. (avx+osxsave is not supported by CPU)
