NetBalancer Free can set and monitor your download and upload transfer rate priority for applications.

Browse and do any internet activity comfortably even when your download manager or torrent client downloads huge files from the web - just lower their network priority with this app.

Applications with a higher network priority will gain more traffic bandwidth than those with a lower one.

High priority
Normal priority

Set download and upload speed limits for a process
