Ah, I see.
Note that you sent this mail from tk@xxxxxxxxxx, which is the same
account you used when you said "sent it from the wrong account". A
mistake, or have you subscribe this account as well?

86 MB/s from the original almost 200 MB/s is actually quite good for a
HVM domU. My results so far seems to indicate that PV disk performance
is close to dom0, while HVM with PV drivers about half of it.

I don't understand why your Windows numbers is so low though. I'm out of ideas.
