Just another "me too", I guess.
I never used OneDrive before, but after upgrading Office to 2016 (ProPlus, not 365) it has become the default location for saving documents, so I decide to try it in certain cases.
Transfer speeds are abysmal. My internet connection is a corporate one, not a simple DSL with a "pro" account, but a dedicated leased line.
It is 200 Mbps symmetrical with bandwidth guarantee, slower than most DSL and cable accounts promise as maximum, but with a _guarantee_ on that speed from here to the provider's peer connections to the outside world and back.
Online bandwidth tests show that I effectively get that speed without any problem, to and from speed testing sites hosted outside of my provider's own network.
Transfer speed down from OneDrive fluctuates between 150-300 kBps (bytes) this morning, let's be friendly and call it roughly 2 Mbps (bits) average.
