Unable to control the network bandwidth using fiddler in spite of custom rules?

问题

I want to run few performance tests with different n/w speeds and read that fiddler can help in that.

I modified the request-trickle-delay and response-trickle-delay params in the custom rules script file and selected the Simulate Modem Speeds flag.

Nevertheless it does not help in controlling the bandwidth and the download time continues to be the same when I try testing my settings. Even when I set the delay to "5000" it does not show any difference.

I believe I am missing something though am not able to find that out. Any inputs towards this is appreciated.

        oSession["request-trickle-delay"] = "300"; 
    //oSession["request-trickle-delay"] = "5000"; 

        // Delay receives by 150ms per KB downloaded.
        oSession["response-trickle-delay"] = "150"; 
        //oSession["response-trickle-delay"] = "5000";
