Your download speed from your box depends on various factors.

You can only download from your box at a maximum of your line speed. Also it depends on your location vs your seedbox location and transit speeds. For example if your seedbox is in EU and you are in US its likely you will get slow speeds from your box because of low transit priority. You could get a US seedbox but then you would likely get slower torrent speeds because majority of torrent servers are in EU so its cache 22 really.

It could also be that you're trying to download a large single file which can also reduce speeds. If you are trying to download one large file its better to split it server side or to segment it using your FTP client. A client that can do this is CuteFTP and also SmartFTP.
