Network tools that simulate slow network connection

Question

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.

Answer 1

Hello,

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

Best of luck.

Answer 2

I've successfully used TMnetSim (bottom of the page, under “Other Tools” - the link says something like “ZIP: TMnetSim Network Simulator version 2.4 32-bit (600KB)”

It's not just for websites - you can slow connections to any TCP port. I was using it to simulate a slow SQL Server (port 1433).

Answer 3

try Traffic Shaper XP you can easily limit speed of IE or other browser with this App and its also freeware

Answer 4

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).

Answer 5

I am resurrecting this thread because I hade the same need recently. Amazingly I discovered that Fiddler can be used to do that by customizing the rules and adding this line oSession["response-trickle-delay"] = "150"; in the section OnBeforeResponse. Fiddler is really amazing

DummyNet

Try this FreeBSD based VMWare image. It also has an excellent how-to, purely free and stands up in 20 minutes.
