I developed an application that uses a website API and I got feedbacks that it freezes for almost 30 seconds, and that is due to their poor bandwidth (5Ko/sec downloading).

I have a good internet speed, so a feed with 1Mo wont make more than 3 seconds, I want to know if there is any software that allow me to limit the bandwidth that I want, even under 10Ko/sec.

what's the best app for that?

I'm going to assume you are on Windows XP or Vista since if it were something more interesting (linux or Mac) you would have said so.

I haven't tried it myself, but this may do what you need and it is free: Bandwidth Shaper XP

  • +1 for 'something more interesting' :) Commented Jul 31, 2009 at 7:11

Not sure about an app but you could try to use functions of your router to limit bandwidth, especially with some of the Linksys models like WRT54G that can be loaded with 3rd party firmware for extra features like that. Maybe use QoS somehow?

  • +1 - Router-based solutions are the most painless - no additional software to add, assuming your router supports it. Commented Jul 31, 2009 at 2:30

you can use Network Emulator tool kit to do this.

YOu can find an article explaining how to use it here. http://www.gonetdotnet.info/posts/how-to-test-an-application-in-limited-bandwidth

    See superuser.com/faq#promotion. Since it's your own site, at least add a disclaimer. Also, it would be a more useful answer if you would actually explain here, and not just give a link.
