Below article describes how to tweak Windows Server to allow busy systems perform much better. The purpose of it is to simply avoid exhaustion of TCP/IP stack by decreasing time required to dispose of "dead" (TIME_WAIT) connection. IN most cases these connections are no longer re-usable and quick turn over makes system behave much faster.




  • Windows (generic)



  1. Start Windows Registry Editor

  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

  3. On the Edit menu, click New, DWORD Value, name TcpTimedWaitDelay, and then add the following value to reduce the length of time that a connection stays in the TIME_WAIT state when the connection is being closed. While a connection is in the TIME_WAIT state, the socket pair cannot be reused. Available value in seconds is 30 (minimum) and 240 (maximum) in decimal or 1e and F0 in hexadecimal

  4. Close Windows Registry Editor and reboot the server
