Ok, you seem not to know what Mbit is vs MByte, since 3Mb/s (small b means bit not byte), is nowhere near 240 MB/s, so, this is quite impossible.
Secondly, lateron you say you download with even more speed, namely 350MB/sec..
All in all very very impressive for a DSL line with just 3Mb/s!!
So what is your real speed? (Mb = Mbit, MB = MegaByte)
Anyway, back on track about the slowdown.. this is not to blame on BitTorrent itself. It's about your settings for it.
I have a 60Mb/s (that is arround 7MB/s) connection here at home, and i get depending on the seeders available in relation to the leechers, full speed often.
(it's more rule, than exception for that manner)
even when i had a DSL line (20Mb/s). I got quite a good ratio, my top speed for everything was max. 11Mbit/s (that's because i was to far away from the Telco center, thus dropping my speed significantly overal.)
but again with torrents, i would regularly got 11Mbit/s on that line.
I guess you need to check your settings. (the max speed for uploads, the max for downloads, max connections per torrent, max upload slots, all those things) Also make sure, your upstream portnumber is open in your firewall, otherwise the tracker cannot find you.
