Can anyone inform me of latency?

Hello,

Specifically how can one change the latency for windows nt? I am running from a WAN setup and I was wondering how to increase or decrease latency so I wouldn't recieve time out errors. Thank you for any information.

NT4 uses an 8K TCPWindowSize as default, Windows 2000 uses a 16K Window. Also, Windows 2000 includes support for Selective Acknowledgements by allowing only lost packets to be resent. For details see:

However, it is also possible to improve individual application performance by writing more efficient code (SQL, for example). SQL 7.0 also allows you to change the IPC from Named Pipes to TCP/IP Sockets.
