overall speed of a standard glacier restore? can you do multiple restores at once? Just for some additional info - i looked at the history tab to see how quickly it's downloading files. The last 10 or so files range in size from 26-30MB. This is how many seconds passed between each download of the files: 11, 7, 12, 10, 2, 11, 6, 2, 13, 1 - so that averages out to 7.5 seconds per file.
That's pretty slow - if it was downloading at 100mb/s it should be able to download each file in about 2-3 seconds. So in effect, i'm getting download speeds something like 30-50mb/s
Oh and to answer your previous question - i'm using the ohio location, and I am in michigan, so it's right next door to me.
If i had to take a guess right now - my guess would be that CB is only downloading a single file at a time. I'm not sure if that's because glacier only allows one download thread or if there's some other limitation.
