Simulate a slow internet connection on a local host

Question

iam, using C #, asp.net and iis, I want to simulate a slow internet connection on my computer to test my application.

Is it possible that I can control iis bandwidth.

please do not offer

System.Threading.Thread.Sleep(someDuration); 

in a C # file.

Answer 1

You can run Fiddler and use its throttling to simulate a slow connection.

Note that you will need to navigate to your computer name, not localhost . ( localhost. should also work)

Answer 2

Fiddler will do this for you.

Answer 3

You can find or create a proxy server that provides customizable speeds and customizable speeds. The proxy server will receive a request from the client, make a request to the server, receive a response, then slowly send the response to the client. (He probably uses some sort of Thread.Sleep (x) between sending each byte of the response to the client.)

Answer 4

After a little search on the Internet, I did not find freeware / FOSS on win32 that does the job for arbitrary ports.

I have a server under testing that listens on port 13000 and a test client that has a custom send port. Many Internet-only tools turn the throttling tunnel from port 80 into something customizable, but my server will never listen to port 80.

Does anyone know something like the unix 'tc' command?

Answer 5

This is not related to C #, but I would recommend slowing down the system network (or the vm network ..), it will be much easier to play. On linux we can use tc .

sudo tc qdisc add dev wlp3s0 root netem delay 500ms

To disable it:

sudo tc qdisc del dev wlp3s0 root netem
