Why is the network speed slower after upgrading to XP system

Q: After upgrading my operating system from Windows 98 to Windows XP, I feel slower when I use broadband Internet access. The software and drivers are installed properly. What is the solution?
A: You can try the following methods.
1. First look at the issue of driver version and application compatibility, you can download the latest driver from the device provider website to install.
2. You can maximize the bandwidth utilization by setting the Windows XP. The specific steps are: select “Start →Run" on the system desktop, and the "Open" dialog box appears. Type and run the “gpedit.msc” command to open the "Group Policy" window, and then from the "Administrative Templates", find the "Network" project, there is a "QOS Packet Scheduling" & rdquo; Item, after expanding, you can see a “Restrict bandwidth reserved” item under the “Settings” column on the right side of the window. Double-click the item to see the “Bandwidth Limit” here. The default value is 20%. You can change this parameter to “enabled” and change the "bandwidth limit" value to “0%” to maximize bandwidth utilization.
