FYI, I know there is at least one case open with Microsoft Support on this. Lots of variables come into play, so hard to narrow down to what might be the issue. When doing speed test comparisons or standalone tests, make sure you're doing HTTP transfers. In one instance someone was comparing the task sequence content download in WinPE (HTTP) to a straight-forward SMB robocopy - not the same.
Also re a question from original message - using an older WinPE version (e.g., 4) to deploy a newer version of Windows (e.g., 8.1) is not supported. It's backwards compatible two version, but not forward compatible. Might still technically work - YMMV.

(Is it supported to use WinPE4.0 for deploying Win8.1.. as a temp workaround right now?) I have seen it on 2 different customers and in my internal lab using Server2012/CM12R2/MDT2013/WinPE 5 (VMware workstation in my lab and VMware ESX 4.1u1 at the customers site) Anyone have a suggestion in this issue ?
