I don’t know what is causing the slowness between vm and fog imaging, but that’s what I see as well. I’ll see it start out, not fast, but not slow, to almost a crawl. I, too, only have vm’s that I can use to test so I’m much in the same boat, though when I deployed my wife’s laptop, it was not slow at all. Imaging was around 2.5 ~ 3.5 GiB Min on upload, and deploy was close to 4.0 and 5.0 GiB. I have gig switches at the house.
