    Parameters of Ancillary Function Driver (AFD) for Windows 7

    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\AFD\Parameters]
    "DefaultReceiveWindow"=dword:00080000
    "DefaultSendWindow"=dword:00080000
    "DynamicSendBufferDisable"=dword:00000000
    DynamicSendBufferDisable must be added to work because this parameter disable Winsock send autotuning and, will force winsock to use larger buffers..!

    Requires Restart PC

    C:\Windows\System32>netsh winsock show autotuning
    Winsock send autotuning is disabled.

    when I set in netsh: netsh winsock set autotuning on, I get this message => Winsock send autotuning is disabled.
    when I set in netsh: netsh winsock set autotuning off, I get this message => Winsock send autotuning is enabled.

    Something it seems to be inverted in netsh with that settings ! on is off and vice-verse, whatever !

    These parameters improve your SEND speed connection over Internet on broadband!

    KEiGHT, you are right that the netsh commands are reversed, have you actually confirmed that it changes in outgoing packets with a packet sniffer ?
