https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #6 from karl@pielorz.com --- (In reply to rainer from comment #5) 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 te= st on - that is backed by a local SATA / SAS disk on XenServer (i.e. not going through ScaleIO?) -Karl --=20 You are receiving this mail because: You are the assignee for the bug.=
