There is NO way to say for sure because we simply have NO control over
the remote site you are uploading files unto. We can only be guessing.
As I already said my guess was Microsft Azure was throttling (slowing
down) concurrent connections from the same IP address in order to
prevent one client from clogging up too much bandwidth.

HttpClient 4.x default settings are reasonable enough. There is really
not much material to put into a guide like that.
