This is / should be extremely easy using Fiddler.
Here is a simple walkthrough on how to do this:
1. Go to Fiddler site and download Fiddler latest version (http://www.fiddler2.com/fiddler2/)
2. Install it and start it.
3. Click on Rules -> Customize Rules:
4. An instance of notepad should open. Find the line that says something like "oSession["request-trickle-delay"]":
This setting tells Fiddler how much milliseconds should halt the request. (not quite sure how a request halt will help you though)
5. Find the line that says "oSession["response-trickle-delay"]" and change it:
Save the file.
You should have a connection limitation.
Now, when you want your connections slowed down, you will need to check the following option:
6. Rules -> Performance -> Simulate Modem Speeds (should be checked):
Please do not forget to switch off fiddler when you don't need it as you may find yourself wondering why is your connection significantly slower than usual ;).
Hope it helps someone out there.
