How to test the program on a slow Internet connection?

How to programmatica开发者_StackOverflow社区lly you can slow down access to the internet?

As suggested by VDesmedT, Netlimiter is a great tool. I used it some years ago to not to claim our full corporate internet connection during working hours while downloading big ISO's.

But I would suggest a dedicated box that was build exactly for that purpose, like this one.

http://wanem.sourceforge.net/

It is a standalone appliance (or virtual machine) where you can simulate a WAN line with many aspects like:

• Bandwith
• Package Loss
• Data Corruption
• Different Up/Download speeds

There are more tools like that out there (search WAN emulator at your favorite search engine) but that one looks promissing, even if I never used it before but only a similar, commercial appliance.

There are a lot of bandwith limiter on the Net, NetLimiter is a very good at this.
