[platform-update-dev] Parallel downloading

["Dejan Glozic" <dejan@xxxxxxxxxx>]

Thinking a bit more about the recent suggestion (download manager that is
capable of downloading several plug-ins in parallel by opening multiple
connections).

Jeff, are you implying that connecting with one stream and downloading
bytes does not use the connection to its full capacity and that we can tap
into that unused capacity with more connections?

I would be surprised because my experience with downloading three zip files
of a comparable size from using a browser (with three separate download
progress dialog shown) indicates that throughput goes down to roughly one
third (hardly surprising :-). If you add overhead of managing processes, I
cannot see how we can gain anything this way.
