As discussed previously,
we're going to enable RFC 1323
Window Scaling
and increase the default TCP receive and send windows to 1 MB. By default Windows
2000 and XP do not offer window scaling options, but will accept them if offered
by the other side. To make our changes, we'll need to modify the following registry
keys under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters and reboot
the system.
Tcp1323Opts = 3
TcpWindowSize = 1048576
GlobalMaxTcpWindowSize = 16777216
You can edit the Windows registry with Registry Editor. To start Registry Editor
issue regedit at the command prompt or in the Run box. In this image, you can
see the various options being set. Remember to select the radio option for Decimal,
otherwise your values won't mean what they should.
