I would like to find response time of an application, if it is accessed thro' 57kbps modem.

1. Our application is hosted on net
2. Application will be accessed by different people at different location through 57kbps modem.
3. From some places 2 or 3 systems (with proxy) use the same 57kbps.
4. Response time to be calculated for the client connected thro' 57kbps.

I would like to simulate the above point 3 and 4 with qaload

thanks in advance
