Network Speed Simulation

How does the Network Speed Simulation in the Vuser Runtime Settings work? Does it calculate the transaction response times at different speeds based on the size in bytes of the HTTP responses?

That is, if you set the Vuser setting to run at 1 MBs as a custom speed, how does LoadRunner determine what the response time for a transaction should be?

Does it take the size in bytes for an HTTP response, and then determine based on bytes per second how long the response time should be?

Bandwidth throttling doesn’t predict the response time. It only limits the amount of bandwidth available to a process or thread using the operating system’s own control.

If the bandwidth required exceeds what is available, this will impact response times and be reflected in the results.

But setting this doesn’t automatically result in higher response time calculations.
