Disabling the QoS Packet Scheduler
Many have noticed that strange entry under TCP/IP properties - that mysteriously appeared when they upgraded to WinXP.
QoS (Quality of Service) Packet Scheduler is a network stack component designed to provide reporting on the speed and response time of the network for applications that are designed to use it. If you're not running a server, the QoS Packet Scheduler is probably not going to make a noticeable difference in your network speed. In fact, disabling it may speed things up a bit !!
Common effects of QoS include slow file access over a peer to peer network, and it may take forever for your Windows XP computer to access files on a Windows 98 computer over the network.
Here's how to disable it :
1) Click Start and click the Control Panel.
