    Checksum Offload

    According to Microsoft;

    *IPChecksumOffloadIPv4 IPv4 Checksum Offload > 0 = Disabled
    Why in SG TCP Optimizer is Enabled: 0 ?

    registry of Windows says:

    "DisableTaskOffload"=dword:00000000

    So? Is Enabled or Disabled !?

    Why do you mix words ?

    *IPChecksumOffloadIPv4 is one of Offload Service Registry Key.
    SG TCPO using Global TCP/IP Protocol Registry Key.

    Code:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\DisableTaskOffload
    Setting this value to one disables all of the task offloads from the TCP/IP transport. Setting this value to zero enables all of the task offloads.

    Now you see what I am talking about ?



    so there must be "enable: 1" and disable: 0

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\DisableTaskOffload < For Windows 7
    *Setting this value to one disables all of the task offloads from the TCP/IP transport. Setting this value to zero enables all of the task offloads.

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ipsec\EnabledOffload < For Windows 2000/XP
    *Setting this value to zero disables Internet protocol security (IPsec) offloads from the TCP/IP transport. The offloading of TCP/IP checksum tasks, large send offload version 1 (LSOV1),
    and large send offload version 2 (LSOV2) are not affected. Setting this value to one enables IPsec offloads.

    So there must be Written Enabled Offload or Disable Task Offload , why Checksum Offloading ? Most of the people have no idea what's for and are confused !
