BitTorrent slower than other clients?

[fabthi]

Hi everybody

I have been using a different Torrent client (Vuze) since ever, but it requires to upgrade to a paid version for burning DVDs (well, I can actually burn them but they come up without audio) and for that I wanted to try using BitTorrent.

I noticed it is a lot slower than my usual Torrent client and I am wondering why and if there's anything I can do in the settings to improve download speed (which is about 10-15% of Vuze's speed for the same file).

thanks for the help
