There were huge changes. The same for userspace. BTW do you know that TC7 uses dm-crypt as backend? So with the same mode and alignemnt you should get the same results (except chained ciphers in TC). > As you can see, there's almost a 4 minute difference.

Use the same mode in cryptsetup cryptstup luksFormat -c aes-xts-plain64 -s 512 ... I would really wonder if speed differs, TC7 uses dmsetup to configure dm-crypt mapping on Linux :-) It uses userspace (and FUSE) only for old containers and some magic for hidden container.
