Change Your Bandwidth Reserve Setting

Want to speed up your connection speed on your computer?

Windows XP reserves about 20% of your bandwidth for Quality Of Service or QoS traffic. This type of traffic is not necessary at all times and you can utilize this 20% that Windows uses and re-route this extra bandwidth to your primary connection or services. Performing this tweak will yield a faster connection due to freeing up an extra 20% of bandwidth.

    Correction of some incorrect claims about Windows XP QoS support
    There have been claims in various published technical articles and newsgroup postings that Windows XP always reserves 20 percent of the available bandwidth for QoS. These claims are incorrect. The information in the "Clarification about QoS in end computers that are Running Windows XP" section correctly describes the behavior of Windows XP systems.
