HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NIC-id}
There will be multiple NIC interfaces listed there, for example: {1660430C-B14A-4AC2-8F83-B653E83E8297}. Find the correct one with your IP address listed. Under this {NIC-id} key, create a new DWORD value:
TcpAckFrequency=1 (DWORD value, 1=disable, 2=default, 2-n=send ACKs if outstanding ACKs before timed interval. Setting not present by default).
==================
TcpAckFrequency=1
in Optimizer, shows as Enable: 1 NOT Disable, why is that ?
Default: n/a
Enabled: 1
Disabled: 0 (in fact is 2=disable)
setting to 1 is enabling disable or what ?
)how should it be after all ?
This should look like this one;
Default: n\a
Enable: 1
Disable: 2 (recommended by Microsoft TcpAckFrequency=2 / which disable nagle) msdn.microsoft.com/en-us/library/cc558565%28v=bts.10%29.aspx
The TcpAckFrequency value can only be set after installing Hotfix 815230, described in Microsoft Knowledge Base article 815230, “Changing the TcpAckFrequency value to 1 does not have any effect” at support.microsoft.com/kb/815230.
TcpDelAckTicks=0 set in registry, showed by Optimizer as defaut: n\a !!! disabled=2
