Network tools that simulate slow network connection

I would like to visually evaluate web pages response time for several Internet connections types (DSL, Cable, T1, dial-up etc.) while my browser and web server are on the same LAN or even on the same machine. Are there any simple network tools or browser plug-ins that slow down network bandwidth to simulate different real-world connection scenarios.

I appreciate any input on that.

On Linux, see netem: the kernel already contains support for traffic shaping, and can simulate high latency, low bandwidth, packet losses, and all sort of other adverse conditions, even on a loopback device (so you don't need a real, physical network to test across).

My work uses this tool, and it seems quite good: http://www.dallaway.com/sloppy/

Best of luck.

If you'd like a hardware solution, Netgear has a series of cheap ($50 or so) switches that do bandwidth limiting. Netgear Prosafe GS105E and similar switches are worth investigating.
