XP: Speed Up Browsing/Download Speeds
When you browse or download from the internet in XP a small portion of your bandwidth is reserved for quality control purposes. In most cases this is a throwback to older systems and is really not required.
This tip removes that reservation and helps speed things up slightly.
Open up the Group Policy Editor (Click on Start->Run type gpedit.msc click ok) and then browse down to the following branch on the left hand side.
Local Computer Policy, Computer Configuration, Administrative Templates, Network, QoS Packet Scheduler
After you've highlighted 'QoS Packet Scheduler' in the left window you can double click 'Limit Reservable Bandwidth' in the right window.
Click on the Enable radio button and set the figure to '0%'.

Cheers for that. Hopefully it will work better. :-)
