Bit torrents killing my internet?

[Divisible by Waffle]

It also depends upon the Bittorent client you're using; some are bigger bandwidth whores than others, and many do have options to cap download speeds as was said before. You might want to try switching to something that eats less bandwidth, and maybe a little less memory at the same time. I've gotten an older machine to crash before just by running Azureus.

EDIT:

OK, I believe I just made myself look like an idiot. I looked up a few clients (Bittornado, Azureus, and one other) and the base bandwidth usage isn't too different between the programs. Not enough to make a significant difference, at any rate. Though you can make it use less bandwidth if you don't seed while you're downloading something else.
