Hello Milan,

I always stay with the stock kernel (Fedora 14) so I don't have to take
care of bug-fixes & security-updates for the kernel :) ...but I'll try
to run a newer kernel If I do the test again.

I had no idea it used dm-crypt! That's great.

Great, I'll do that. I'll perform the tests again (everything equal:
kernel, disk, data, empty buffers, rsync) but I'll use xts this time for
LUKS. I'll report back.
Thanks Milan!
