Windows 10 have an auto-tuning feature which tries to dynamically adjust the receive buffer size for transmission and latency of the link. Free games for pc windows 10. In-fact this feature is present in all Modern Operating systems including Windows 10. So, its a Necessary Feature all together as it manages and adjusts Receive buffer size dynamically.
How to Check if Auto Tuning Feature is Enabled ?
1 – Open Command Prompt as admin by Searching cmd in Windows 10 Search box and then right clicking on the cmd icon and clicking on Run as Administrator.
To determine the optimal receive window size, the Receive Window Auto-Tuning feature. Windows 7, Vista, 2008 Tweaks Check the TCP/IP state. The settings, as well as their default and recommended state are explained. Disable Windows Scaling heuristics. Windows Vista/7 has the ability to automatically change its own. TCP Auto-Tuning.

First you will have to make sure that the problem is caused by a network hardware device that does not support TCP Window Scaling. This is how you will do it: 1.Run Command Prompt as an Administrator. Enter this command: netsh interface tcp show global. Look for Receive Window Auto-Tuning Level. You will have to see what value is written. Apr 13, 2011 Disable TCP/IP “Auto Tuning” in windows 7/vista/windows 2008 R2. On April 13, 2011. 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. In Windows Vista, Windows Server 2008, and later versions of Windows, the Windows network stack uses a feature that is named TCP receive window autotuning level to negotiate the TCP receive window size. This feature can negotiate a defined receive window size for every TCP communication during the TCP. Auto Tuning adjusts the receive windows size continually based upon the changing network conditions. This usually happens if you have a network device (EX: Router, modem, etc.) that doesn’t support RFC 1323 “TCP Extensions for High Performance”.
2 – Now, run the following command given below.
3 – In the output if Receive Windows Auto Tuning Level says Normal, then the Auto tuning Feature is enabled on your PC.

Windows 10 Tcp Tuning Utility
Note: This mechanism is sometimes referred to as 'Dynamic Right-Sizing' (DRS).
The issues mentioned under 'Large TCP Windows' are arguments in favor of 'buffer auto-tuning', a promising but relatively new approach to better TCP performance in operating systems. See the TCP auto-tuning zoo reference for a description of some approaches.
Microsoft introduced (receive-side) buffer auto-tuning in Windows Vista. This implementation is explained in a TechNet Magazine 'Cable Guy' article.
FreeBSD introduced buffer auto-tuning as part of its 7.0 release.
Mac OS X introduced buffer auto-tuning in release 10.5.
Linux auto-tuning details
Some automatic buffer tuning is implemented in Linux 2.4 (sender-side), and Linux 2.6 implements it for both the send and receive directions.
In a post to the web100-discuss mailing list, John Heffner describes the Linux 2.6.16 (March 2006) Linux implementation as follows:
For the sender, we explored separating the send buffer and retransmit queue, but this has been put on the back burner. This is a cleaner approach, but is not necessary to achieve good performance. What is currently implemented in Linux is essentially what is described in Semke '98, but without the max-min fair sharing. When memory runs out, Linux implements something more like congestion control for reducing memory. It's not clear that this is well-behaved, and I'm not aware of any literature on this. However, it's rarely used in practice.
For the receiver, we took an approach similar to DRS, but not quite the same. RTT is measured with timestamps (when available), rather than using a bounding function. This allows it to track a rise in RTT (for example, due to path change or queuing). Also, a subtle but important difference is that receiving rate is measured by the amount of data consumed by the application, not data received by TCP.
Matt Mathis reports on the end2end-interest mailing list (26/07/06):
Linux 2.6.17 now has sender and receiver side autotuning and a 4 MB DEFAULT maximum window size. Yes, by default it negotiates a TCP window scale of 7.
4 MB is sufficient to support about 100 Mb/s on a 300 ms path or 1 Gb/s on a 30 ms path, assuming you have enough data and an extremely clean (loss-less) network.
