It is curious that uploading finished faster than downloading even
though it was moving three times as much data.

In fact, could you run this a few times and collect multiple
measurements? Maybe it was just a transient "fluke" -- some kind of
noise on your network or one of your machines interfered with the
download.

If it wasn't a fluke I wonder if it could be the effect of issue
#1223, which is fixed in trunk (== 1.8.1 release candidate). #1223
should have the impact of slowing downloads, but I'm not sure by how
much.

Anyway, is the overall performance good enough for your current uses?

Regards,

Zooko
