Haa ..
The tweak below allows for tweaking or disabling Nagle's
alogrithm. Disabling "nagling" allows for very small packets to be
transferred immediately without delay. Note that disabling Nagle's
algorithm is only recommended for some games, and it may have
negative impact on file transfers/throughput. The dafault state
(Nagling enabled) improves performance by allowing several small
packets to be combined together into a single, larger packet for more efficient
transmission. While this improves overall performance and reduces
TCP/IP overhead,
it may briefly delay transmission of smaller packets. Keep in mind
that disabling Nagle's algorithm may have some negative effect on
file transfers, and can only help reduce delay in some games. To
implement this tweak, in the registry editor
(Start>Run>regedit) find:
This setting configures the maximum number of outstanding ACKs
in Windows XP/2003/Vista/2008:
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).
For gaming performance, recommended is 1 (disable). For pure
throughput and
data streaming, you can experiment with values over 2. If you try
larger values, just make sure TcpAckFrequency*MTU is less than RWIN, since the sender may
stop sending data if RWIN fills witout
acknowledgement.
Also, find the following key (if present):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters
Add a new DWORD value:
TCPNoDelay=1 (DWORD value, 0
to enable Nagle's algorithm, 1 to disable, not present by
default)
To configure the ACK interval timeout (only has effect if
nagling is enabled), find the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NIC-id}
TcpDelAckTicks=0 (DWORD value,
default=2, 0=disable nagling, 1-6=100-600 ms). Note you can also
set this to 1 to reduce the nagle effect from the default of 200ms
without disabling it.
This is wat i found out .. Do i just input one DWORD value? Or
do i need to input the rest as stated above?
