Wmloadsimulator.exe: Windows Media Load SimulatorNEW

Server-only: This tool is included in the Windows 2000 Server Resource Kit only.

Windows Media Load Simulator is a testing tool used to simulate large numbers of users streaming audio or video data from a Windows Media Server.

Windows Media Load Simulator must be installed on a client computer and used to test the capacity of the Windows Media Unicast Service on a Windows Media server. The load simulator simulates a high client demand by initiating a large number of client requests for streams in order to potentially overwhelm the system and network resources of your site. Each instance of Windows Media Load Simulator can request streams for up to 200 simulated clients.

To create an even larger demand on the Windows Media server, you can run multiple instances of Windows Media Load Simulator on a single client computer or on multiple client computers against the same Windows Media server. For example, if you want to determine if your Windows Media server can handle 1,000 client requests for unicast content, you can run five instances of Windows Media Load Simulator, each configured to simulate 200 clients, on one client computer. Or you can run a single instance of Windows Media Load Simulator, each configured to simulate 200 clients, on five client computers.

Windows Media Load Simulator also allows you to create user names and passwords for the simulated clients. The Windows Media server must process this information and authenticate each user, which consumes even more server resources. Windows Media Load Simulator supports authentication using Basic User Authentication and Windows NTLM on the Windows Media server.
