I need the throttle to be set, or else I spend about 30 seconds waiting for it to go up in several rounde.
To that end I have implemented an option to set an initial throttle.
With my current networking setup, the throttle need to be about 0.25 for the file to upload without error.
Setting it to 0.2 means that every file starts uploaded without more than a few seconds delay.
A diff(1) file is attached.
