Internet speed can be optimized to make your Internet Connection Speed better. In this trick we can increase the Internet speed by 20% . This tip is designed for the BROADBAND speeds in XP but will work for 56kbps modems too. Windows XP reserves 20 per cent of your Internet bandwidth for Quality of Service. This is unnecessary, and can be disabled so that you get good Internet speed.
QoS Packet Scheduler is a method of network bandwidth management that can monitor the importance of data packets and depending upon the priority of the packet, give it higher or lower priority or bandwidth levels. It’s not very useful unless you’re using apps which are QoS-aware or running a server, so you can gain some network overhead back by turning it off.
Procedure to Increase Internet Speed:
* Open the Group Policy Editor by going to Start> Run > Type gpedit.msc > [Enter]
* This will open Group Policy Editor.
* In the left-hand column in the opened window, navigate to
Computer Configuration > Administrative Templates > Network > QoS Packet Scheduler.
* In the right column, double-click “Limit reservable bandwidth” and select Enabled.
* Change the Bandwidth Limit to 0 and click OK.
* Close Group Policy Editor.
That’s it! Effect will be immediate on some systems and some systems may require a reboot.
It really helped me a lot
