Ok, so 'like for like' test see's better performance.

I'm not overly familiar with dc3dd - maybe it's using a "really small block
size" - and  on your setup, this is causing an issue (maybe look at the ssz /
bufsz options)

Do you have any 'local storage' on XenServer (or can you create some) - i.e.
something you can map to a FreeBSD VM - and repeat both the dc3dd and dd test
on - that is backed by a local SATA / SAS disk on XenServer (i.e. not going
through ScaleIO?)
