Fine tune Internet connection speed: Tip on changing QoS parameter.

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
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.
