Vista Tweaks
Heres a Little guide on how to improve connection speed and stabilty!
Vista tweaks Index 1. About Vista tweaks and this guide 2. How to open the Command Prompt window 3. The Tweaks 1.0 This is a quick easy guide to doing the safe tweaks that will bring you the greatest benefit. There are other options for most of the commands dealt with here. If you want to play at a deeper level, there are many sites that will give you all the commands, not least the Microsoft site, where most of this came from. The Vista OS has changed the way it deals with controlling the data flows to and from the LAN and the Internet and it is now reasonable automatic. There are a few tweaks that can be done to get the best out of the computer for broadband. These tweaks are unlikely show any miraculous increases in speed as can happen with the XP RWIN, what you will notice is a definite improvement in your operation at busy congested times and when you download large files. This is because Vista is continually adjusting its RWIN etc and these tweaks will allow the OS to use all of its facilities not just the default ones. But you should notice a difference. Like RWIN there is great debate about which tweaks work and which do not, I have only included tweaks that I have tested and have worked on one of my two versions of Vista. If you would like to dig deeper and try other things I would suggest that you start with http://www.speedguide.net/read_articles.php?id=2574 or http://www.kitz.co.uk/adsl/vistaTCPtweaks.htm © Hatari 2008 2.0 How to open the Command Prompt window All of the commands entered for these tweaks need to done using the Command Prompt Window in what is known as elevated command prompt, it is to you and me “Running as Administrator. .It is important that the Command Prompt Window is open so that it is “Running as Administrator”. If you do not, you will get errors rather than nice “OK” and have to start again. A tips when using the Command Prompt Window. Copy the command from this article by highlighting and using copy, the move the cursor into the Command Prompt Window right click and select paste. That should save you a lot of typos and repeated entries. After you have entered a command in the Command Prompt Window and hit Return, and all is OK you will get “OK” on the next line. If you get errors then you are not in Command Prompt Window or you have made a typo. Please try opening it again. To open the Command Prompt Window: Click start, Click All Programs, scroll to Accessories and Click to open Accessories. Find the Command Prompt and right click it, and left click "Run as Administrator" As small window will open, click Continue, and a black window will open. The Command Prompt Window. © Hatari 2008 3.0 The Tweaks Into the Command Prompt Window(the Black Window), enter: netsh int tcp show global Return This will display a list similar to the one below; this is how they should look if all is correct. You need to check your list against this and note which items are not correct. TCP Global Parameters ---------------------------------------------- Receive-Side Scaling State………….: enabled Chimney Offload State…………………: enabled Receive Window Auto-Tuning Level….: normal Add-On Congestion Control Provider..: ctcp ECN Capability………………………………: enabled RFC 1323 Timestamps………………….: disabled Is Explicit Congestion Notification enable on your system Next you need to run a test to see if your system supports ECN (Explicit Congestion Notification) some system support it other do not. To run the test go to http://www.microsoft.com/windows/usi...d/default.mspx and follow the instructions. You are looking for the result of the ECN test that is under "Traffic Congestion Test". If it is supported you can enable it. Now to tweak your Vista. Receive-Side Scaling State needs to be enabled. The command is: netsh int tcp set global rss=enabled <Return> Chimney Offload State needs to be enabled The command is: netsh int tcp set global chimney=enabled <Return> Receive Window Auto-Tuning Level needs to be normal The command is: netsh int tcp set global autotuninglevel=normal <Return> Add-On Congestion Control Provider needs to be set to ctcp This may not appear to be in your list. If you do not think the Congestion Control Provider is on yourlist enter the command and it will appear. The command is: netsh interface tcp set global congestionprovider=ctcp <Return> You should only enable ECN Capability if the Microsoft test said it could be enabled on your system. The command is: netsh int tcp set global ecncapability=enabled <Return> Now do another netsh int tcp show global <Return > Finally, check if has all taken. Your list should look like the one below. TCP Global Parameters ---------------------------------------------- Receive-Side Scaling State………….: enabled Chimney Offload State…………………: enabled Receive Window Auto-Tuning Level….: normal Add-On Congestion Control Provider..: ctcp ECN Capability………………………………: enabled RFC 1323 Timestamps………………….: disabled any questions just ask!

Interesting.
You may want to explain what each tweak does to your system and why it is an improvement. Also some formatting would be beneficial.
