How to downgrade a 120mbit line (our current connection) temporary to a 10mbit to test what our potential clients with less speedy internet are experiencing as the website loads?

At this moment everything loads in less than a second: For us there is now No Way to EXPERIENCE the built up of the pages visually as a user. Ive searched the plugin directory of FireFox over and over but nothing I could find there. Any and all tips are welcome!


yeah would be nice though to just have some firefox plugin, you know,, where you can set the maximum virtual kbit, that way you can even experience how a person with 56K would experience. NOT that anyperson in the world would use that now, but just to dive into nostalgia for a minute and feel the internet experience of ten years ago (or a far far away user from other side of the world visiting your server... very handy to limit the speed to, say 1 Mbit.

As per Tom's comment, if you set your pc/switch port to 10mbit, then it's very easy to replicate this

That's still relatively fast, and affects throughput more than latency, which may be a more serious real-world issue. – mattdm Dec 14 '10 at 15:33
Great idea and so easy to change! Thanks – Sam Dec 14 '10 at 23:29

So you need to throttle de bandwith just on your PC or at a Gateway level ? Models and versions?

Fiddler is a very good tool which has presets for bandwith throttling AND delaying of requests to simulate high latency networks.

To enable this go to Rules / Performances / Simulate Modem Speed, note that you can set the delay/throttling yourself using the Rules / Customize Rules.

The best tool I know about is Comcast.
With it, you can limit your bandwidth as well as your latency and packet-loss.

As the owner of the project say "Simulating shitty network connections so you can build better systems."

At first I thought it was a joke but it's actually serious and looks nice. – user186340 Apr 2 '15 at 16:50
@AndréDaniel and it works very well – Martin Magakian Apr 9 '15 at 14:29
