Maybe test this dm-crypt performance proposal too:
   http://people.redhat.com/mpatocka/patches/kernel/dm-crypt-paralelizace/current/series.html

Just note, this is not yet stable repository and final patches
will change (or perhaps some patches will not be committed,
depends on testing output).

IOW - if you can experiment with your data, try it, otherwise please wait
until it is in upstream repo.

Thanks,
