If another torrent client is installed on the same server as TorrServer. in which the same torrent is added and the file is already completely downloaded, then I believe it will work much faster if peers on 127.0.0.1 or the local network are taken first to watch the video
I don't think LSD is implemented, but it could be possible to preference local IPs. How are you adding those? I suspect having private IPs returned from trackers won't be handled well currently.
