Hi Mike,
I took your challenge and did some tests with a set of files of 150MB.
What I did was to compare the speed of data transfer in my very small home
servers, both using Intel Desktop Board D945GSEJT with processor Atom N270.
Configurations:
server 0:
1 GB of RAM
OpenBSD 5.2
Samsung SATA 2 disk HD103UJ
Samsung SATA 2 disk HD103SJ
server 1:
2 GB of RAM
FreeBSD 9.1 & Linux kernel 3.2.29
Seagate PATA ST3160023A
Default configuration/chipers for softraid (OpenBSD), geom & geli
(FreeBSD), and cryptsetup luks (Linux) were used.
>From my search, default chipers are:
Linux - AES-CBC-ESSIV:SHA256
FreeBSD geom - 128 AES in CBC mode
FreeBSD geli - 128 AES-XTS
OpenBSD softraid0 - 256 AES-XTS
I don't know enough about encryption, but it seems that
OpenBSD's softraid is the best one and also most demandign. Am I
correct?
The command used to copy files was `cp -pR` in FreeBSD and OpenBSD,
and `cp -ar` in Linux.
Each operation was run at least two times, although only one time is
recorded, because the operations returned similar results.
Recorded times for operations in same disk (used HD103UJ in OpenBSD):

Disk operations envolving encrypted partitions on OpenBSD are the
longest ones, even considering that it's using a faster disk.
As I wrote in an earlier post, the cpu is using about 80% during
OpenBSD' data transfers. The OpenBSD's data transfer speeds when involving
encrypted partitions seem to confirm that they are cpu bound, in my
system.
Maybe because of the superior encryption algorithm, maybe not, Atom
N270 processor doesn't seem sufficient to run OpenBSD in encrypted
mode. It's a real pain to use OpenBSD is this mode.
FreeBSD and specially Linux are much quicker.

When using two disks, times for data transfer are shorter, although
unreasonable long for everyday use.
It would be nice to be able to try softraid with 128 AES-XTS instead
of 256, to check apples with apples.
