TCP/IP Configuration
As part of installation in Windows XP, the following registry settings are made
in order to optimize the throughput for WWAN devices.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Table 3 TCP/IP Optimization
Name
Type
Value
TcpWindowSize REG_DWORD 0x40290
Tcp1323Opts
REG_DWORD 0x1
Note:
Setting Tcp1323Opts="0x3" and thus enabling Timestamp might help in some
cases where there is increased packet loss. However, generally better
throughput is achieved with Tcp1323Opts="0x1", since Timestamps add 12
bytes to the header of each IP packet.
