I noticed that even in the browser sometimes the download take an incredible amount of time, it's not slow ... the download didn't even start for a few minutes then starts and ends in less than a second.

Can you set an higher timeout or use a configurable parameter?

That sounds pretty plausible to me - however, I don't spend much time on this anymore, so it might be a while till I get aroudn to it. If you submit a PR I'd be happy to land it
