Quoting /usr/share/doc/cryptsetup/README.keyctl :

    The current state for dm-crypt in Linux is that it is single threaded, thus
    every dm-crypt mapping only uses a single core for crypto operations.  To
    use the full power of your many-core processor it is thus necessary to
    split the dm-crypt device. For Linux software raid arrays the easiest
    segmentation is to just put the dm-crypt layer below the software raid
    layer.

However, this seems no longer true since 2.6.38, cf.

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714806
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c029772125594e31eb1a5ad9e0913724ed9891f2
  http://kernelnewbies.org/Linux_2_6_38#head-49f5f735853f8cc7c4d89e5c266fe07316b49f4c

Therefore encrypting the array (instead of assembling an array of encrypted
disks) shouldn't cause a performance cost. Also, it makes the ramdisk much
easier to configure :-)
