Monitor and Control Internet Traffic with NetBalancer
NetBalancer is an easy to use internet traffic control and monitoring utility. When you download huge files through download manager or torrent client, you may have experienced difficulty browsing the sites or doing any other internet activity. Using NetBalancer you can solve this issue.
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.
NetBalancer is compatible with 32bit version of Windows XP/2003/Vista and Windows 7.
