Throttled Pro optimizes your internet connection and provides "QoS (Quality of Service)" to Mac OS X.
Throttled Pro achieves these results by providing weighted network queues (WF2Q ) that guarantee bandwidth for all your essential network services like web browsing, email, and online gaming. In addition, it provides ACK packet priority which speeds up downloads when you are sending out a lot of data. This combination assures that you get the most out of your internet service.
