If the transfer speed as measure by libcurl stays below 30 bytes per second
for a duration of 60 seconds, the transfer is aborted.

The transfer speed this logic uses as input is the "momentary" transfer speed
- which is based on a moving average over the last 5 seconds.

If you want it to be a fixed time where it should stop, then CURLOPT_TIMEOUT
is more suitable.
