NetBalancer Pro 3.2 (Windows)

Browse and do any Internet activity comfortably even when your download manager or torrent client downloads huge files from Internet - just lower their network priority with NetBalancer. You can use NetBalancer to set download/upload transfer rate priority for any applications and monitor their Internet traffic. Applications with a higher network priority will gain more traffic bandwidth than those with a lower one. The main difference between NetBalancer and other traffic shaping software is that NetBalancer works with priorities, so applications with low priority won't be limited if other high priority applications don't use network.
