Speed simulator is a simple throttling proxy which allows you to see how your site behaves under diffrent connection speeds. It was written by me to test AJAX/Flash loaders and see how much my time took to load.You can simulate various speeds like that of a modem or a ADSL.A pre delay function is also there to help simulate delays due to DNS , connection establishment etc.
See the Demo Video to see how it works.
Installation
Simply unzip from the archive and double click on it to run it.
Usage
Just select the Speed and the Port on which you want Speed Simulator to start on. Once this is done open your favorite browser and set the proxy to 127.0.0.1 and set the port to the select port (default 8080).Now click start in Speed Simulator and open the site that you wish to test.
Really cool little tool !
exactly what I needed…
unfortunately – I have to test through a proxy/vpn… darn!
… It is still an outstanding tool… the way I like it:
simple to install
simple to use
basic in everyway except for the outstanding work it says it does…
Bravo !
We need more software without the frills and bells that works the way yours work !

Dude, thanks! Exactly what I need.
Excellent application for testing! It would be handy to have the option to add more speeds either by the end user or growing the list adding 1.5 Mbps, 3 Mbps, and 5 Mbps.
Thanks for the handy application.
Oh shit you saved me a lot of time and frustration.
Thanks pal.
This Win32 app does the job for Windows users. But Linux users will have to look elsewhere.
Hola
just passed by consedince while searching for some articles 
anyway nice blog Will check it out Later on ,hope you accept me as a follower. thanks ^^
Love the tool!
But, please as Mark said above, can you add a “custom” speed option?
Broadband speeds are increasing and this option would future-proof the tool.
Thanks for your work.

Broadband speeds are increasing rapidly and this would future proof the tool.
Thanks for you work.
