Since last one and half year, I have been working on Windows 7 Operating system and in my experience “Auto Tuning” in windows 7/vista/windows 2008 R2 is the most possible culprit for any network related problems. If you see a network related problem in these operating systems and cannot determine what is the cause, I suggest you try disabling “auto tuning” first.

I know that “auto tuning” is one of the features introduced with windows 7/vista to improve OS operations on network. Basically what it does is, it adjusts the TCP window size to improve the network operations. Though it sounds good in theory, I have seen numerous amount of posts over internet where disabling “auto tuning” addressed many issues like, slow data copy, slowness in email delivery, slow outlook mail caching times, and a few application data transfer related issues. Most of these issues you will see when performing the transfer operations over a WAN link.
So, considering above all, I would like to share the procedure for disabling/enabling “Auto Tuning” in windows 7 environment which may come handy for you in troubleshooting network related issues…
Procedure:
- Open Command prompt with elevated rights
- Run the command netsh interface tcp set global autotuning=disabled
- This disables the auto tuning
- Similar to enable auto tuning back, use the command netsh interface tcp set global autotuningl=normal

Windows has 'Auto-Tuning' set to 'normal' (seen blue above; that is good), but the warning (in red above) is saying that the 'Windows Scaling heuristics' has a role to play as well.
