    Hello guys.
    I have a task to test one web-service of our company on slow connection over 256 kbit\s.

    And for connecting to intnernet ​I am us​ing 4G modem which don't have any options to limit bandwith connection.

    i saw the option named as Simulate Modem speed. It allows to limit bandwith over 56k. But need to limit bandwith in 256 kb\s. How can i do this?

    Hi, Alexander--

    The Simulate Modem Speeds feature is provided in script; you can edit its behavior by clicking Rules > Customize Rules, and editing the script block values:

                if (m_SimulateModem) {
                    // Delay sends by 300ms per KB uploaded.
                    oSession["request-trickle-delay"] = "300"; 
                    // Delay receives by 150ms per KB downloaded.
                    oSession["response-trickle-delay"] = "150"; 

    You just need to adjust the delay to throttle your real connection down to your simulated connection.

    Having said that, if you're using Google Chrome as your client, you can hit F12 and use its richer bandwidth throttling features. These only work for Chrome, but they include many pre-built defaults.
