Setting this parameter to a 1 causes Afd.

Changing this value is not generally recommended.ĭescription: Normally, Windows 2000 completes a Windows Sockets Receive when one of the following occurs: This is advantageous for small amounts of data.

Fast I/O means copying data and bypassing the I/O subsystem, instead of mapping memory and going through the I/O subsystem. The default value was found by testing to be the best overall value for performance. Larger ones are held until the datagram is actually sent. Changing this value is not generally recommended.ĭescription: Datagrams smaller than the value of this parameter go through the fast I/O path or are buffered on send. The default value was found, by testing, to be the best overall value for performance.
Windows afd socket buffer size code#
This value represents a compromise between extra code execution for data copying, and extra code execution in the I/O subsystem and memory manager. (Although this parameter still exists, the TCP stack itself has been hardened against SYN-ATTACK in Windows 2000 therefore, it should not be necessary to use this feature of AFD.) FastCopyReceiveThresholdĭescription: When an application posts a receive with a buffer that is smaller than the current packet being buffered by Winsock, AFD can either make an additional copy of the packet and then copy data to the application buffers directly (which is a two-stage copy because application buffers cannot be accessed directly under the lock), or it can lock and map application buffers and copy data once.
Windows afd socket buffer size free#
Be careful with this value a large value could lead to explosive free connection allocations. DynamicBacklogGrowthDeltaĭescription: Controls the number of free connections to create when additional connections are necessary. See the TCP/IP AllowUserRawAccess registry parameter. This is not used for Windows 2000 transports (like TCP/IP, which manages its own security for raw sockets), which have TDI_SERVICE_FORCE_ACCESS_CHECK set. DisableRawSecurityĭescription: Disables the check for administrative privileges when attempting to open a raw socket. This setting allows administrators to secure older applications that are not aware of this option. A similar effect can be achieved if an application uses the new socket option SO_EXCLUSIVEADDRUSE. Description: This parameter is used to prevent address sharing (SO_REUSEADDR) between processes so that if a process opens a socket, no other process can steal data from it.
