Road Runner Cable and torrenting

A few months ago, I was using Charter and it did a decent job for all things internet. I moved and switched to Road Runner and it works adequately as well, except for torrenting. I'm getting horrible download speeds using both Azureus and muTorrent. I was told there was some sort of trick to fixing this, but haven't been able to find it. Help anyone?

Use an ISP that doesn't provide a shitty service.
