Look at this article in the MS Knowledge base, it directly rebuffs any theorys that turning it off will affect speed:
hxxp://support.microsoft.com/default.aspx?scid=kb;EN-US;q316666
Here is a quote form the MS article:
"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 of this article correctly describes the behavior of Windows XP systems. "
Of course they would say that, so I am still confused. Does any know if it really helps having it disabled or not????????
