I've been trying to leave two bit torrent files running. When I boot the second file up the download speeds for both torrent files drop. I'm using a Linksys WRT54G and Bit Tornado. I have my ports open on the router and when I have a single file running I can reach file download speeds of up to 80k. Is this related to my NAT allocation? Any ideas of how I can fix this? I have NTL 750K broadband. Thanks.
