For the sake of security and stability, Windows XP system reserves 20% of the system bandwidth. For average individual users, this is obviously a bit conservative and wastes valuable network bandwidth. So how to get back these resources? System optimization techniques teach you this method:
Bandwidth is the difference between the highest frequency and the lowest frequency that a communication signal can use. We know that the wider a road, the greater the traffic flow that can pass per unit time. If the transmission rate of network signals is compared to traffic flow, then the bandwidth is equivalent to the width of a highway. Therefore, modifying the original settings of the Windows XP system and fully tapping the 20% bandwidth potential will maximize the Internet speed.
The method to modify this setting in Windows XP system is as follows:
1. Click Start → Run, type: gpedit.msc, and click the [OK] button, you can see the "Group Policy" window in Figure 1.

2. Under the "Computer Configuration" item, click on: Administrative Templates - Network - QoS Packet Scheduler; then on the right side of the window, find the "Limit Reservable Bandwidth" item, right-click the item; in the pop-up In the menu, click "Properties" and you will see the "Limit Reservable Bandwidth Properties" window shown in Figure 2..jpg)
3. In the "Settings" tab, we can see: The default "Bandwidth Limit" value of WindowsXP system is 20%. Change it to a smaller number such as 0 or 5%, click the "Enabled" radio button; then click the [OK] button to save the new settings to the computer.
