Speed Up Windows Vista Network Performance with TCP Windows Tuning

Microsoft KB article 929868 describes a problem which will cause you to experience very slow browsing on certain websites when using Internet Explorer 7 on Windows Vista, and eventually the website might even drop the data completely. The cause is that by default, Windows Vista Enterprise fully supports RFC 1323 and supports a Windows Scaling factor of 8. This issue occurs when a Web site does not fully support RFC 1323 or when a Web site does not support the default scaling factor.

THE QUICK FIX

To work around the slow browsing issue change the Windows Scaling to a factor of 2. First open and Administrator command line prompt. Click Start –> All Programs –> Accessories, right click Command Prompt, then left click Run as administrator. As an alternative you can click Start then type into the Start Search box, or the Run box, cmd, then use the shortcut keys Ctrl-Shift-Enter. (NOTE: After you set a new autotuninglevel you will need to reboot in order for the changes to take effect.) Read More»

If you use a Point-to-Point Protocol connection over Ethernet (PPPoE), you may notice a delay in using the PPPoE connection after startup. By default, there is a 120 second delay
but you can stop this behavior by manually configuring an IP address for the network adapter card. If you do not use a PPPoE connection, you can skip this section.
1. Select Start/Connect to/Show All Connections.
2. Open the TCP/IP properties for your LAN network interface card.
3. Manually set the IP address on the TCP/IP properties to an appropriate IP address and subnet mask for your network.
