Another Bittorrent thread

[Riot_Mac]

I know this has been discussed many times. I cant find an answer.
Ok here is the deal: im on a 3mb cable line and i get great torrent speeds (150-200k) when downloading smaller torrents like 50mb, however when dling bigger torrents (700mb-3gb) i never, i mean never get above 20k it usually hovers around 10k. why is this? it is really annoying me. I have my firewall set to let bittorrents ports (6881-6889) open in my file sharing->firewall settings. Do i have to tweak my airport express settings?
thanks for the help in advance.
what a mac world btw!!!

Smaller files generally have more seeders on them than large ones. How many seeders are on the small torrents you can download fast, and how many are on these big torrents?
