  • First of all, you should be aware that the network simulation provided by VSTS is simply this: the measured response time for each Web test request is increased based on the network speed from the network mix and the content-length of the response.

    The files that define the connect speeds that are simulated are contained in the directory <Program Files>\Microsoft Visual Studio 8\Common7\IDE\Templates\LoadTest\Networks.   There is an XML file that defines each network type.   The value in the file for T1 is 1544 Kbps.   For LAN, the value is 0 which is special value meaning that the response times should not be adjusted at all.   The assumption is that the load test is being run on a LAN and so the measured response time is accurate.  However, you can change the values specified in these files if you'd like.

    Also, if you want to define another network type, you can add another file with the same format.

    After you make any changes or additions, you need to restart Visual Studio for your changes to take affect.
