I have server in local network and i have problem with local speed. On this server I put deluged 1.2.3 opentracker. So when users download torrent for all peers availeble speed is 100 mb, but if in this time i opening ftp and start download I can use full 1 gb channel. Why torrent clients can use all channel?

BitTorrent is a fairly complex protocol...There are many possible issues limiting your speed. (Are you on cable?) Not sure if they apply in a local setting, too, though. –  sr_ Nov 27 '12 at 13:53

Bittorrent uses checksumming and multiple connections. It will require quite a bit more CPU and cause much more disk seeking than FTP. Check the output of top, iostat, vmstat, etc to see what is your limiting factor.

Thanks. Tommorow I'll try another computer. It be core2duo 3ghz 3gb memory. I want install on thic pc ubuntu 12.04 and create raid 0 on 4X3tb hards, for filesystem I'll choose xfs. I have around 2 tb files or 600 torrents. Also I put site on nginx+php, opentracker and deluge. On current machine I use same hardaware cpu load at 10-20% memory using 200-300 mb active uploads in deluge 15-25. –  jared Nov 27 '12 at 19:32
