22. Fine tune Internet connection speed

This tweak deals with QoS parameter manipulation. There have been some confusion as to what can be achieved in real terms by changing the QoS parameter. Microsoft has finally released an article correcting describing the behavior of QoS parameter. I am providing a link to Microsoft web site knowledgebase article http://support.microsoft.com/directory/article.asp?ID=KB;EN-US;q316666. In brief though, this tweak would only work on QoS aware programs and rest of the programs would simply ignore them. Networking Quality of Service (QoS) refers to a variety of techniques that prioritize one type of traffic or program when these operate across a network connection rather than relying solely on "best effort" connectivity. Please click on how to change QoS parameter article using Group Policy Editor (GPEDIT.MSC).By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending enough data to utilize it completely, the unused portion of the reserved bandwidth is available for other data flows on the same host. This default parameter can be changed.
