IIS 6.0 and 7.0 - Network Monitor and TCP Stack Tuning Options

Aug 12, 2013 at 2:07 PM
Hello I am new to CodePlex and Network Monitor. Please can someone advise me here.

I am trying to figure out how to find the values I need to carry out a TCP Stack Tuning exercise where I need to size the TCPWindowSize. On my server, there is no registry key set. My understanding is its: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\TcpWindowSize

The default values are: Gigabit - 65,535 and Ethernet - 16,384

The value needed can be calculated by the formula:

End-to-End Network Bandwith in bytes per second * Bandwith-Delay Product (the round trip measured in seconds.

How can I configure Network Monitor to give me these two values so I can figure out what to set the Registry Key to?

The Top Users expert might give you some data about the Network Bandwidth because it provides a bytes per second, but it divided by endpoint or conversation. I think if you do this for the hardware address in question you can get that value. However, getting the Bandwidth-Delay would require you manually calculate this, perhaps by looking at a TCP 3-way handshake.
