I am a new ReadyNAS Duo user and I have circles under my eyes from staying up playing with all the awesome features of it over the last two nights. I just turned on the BitTorrent client and started downloading the Olympic Opening Ceremonies. In spite of my 15Mb/2Mb FIOS connection to the internet, it was crawling along at about 60K down and 15-30K up until I changed the bandwidth mgmt setting from automatic to manual and left it at unlimited. Speeds immediately jumped to 1-2Mbps down and close to 100-200Kbps up.
This is probably obvious to those more experienced with torrent clients and specifically the RND torrent client, but I thought I'd post it since I didn't see any posts about this important setting.
