      The Exchange Load Generator (LoadGen) document describes installing Exchange Load Generator on a client computer and then steps through configuring, creating, running, customizing, repeating, and stopping the test. Information is provided about the user interface, the XML configuration file, and the command-line program, each of which performs specific functions of the tool. Additionally, there are topics for using System Monitor and LoadGen data, things to consider when looking at test results, and consolidating System Monitor data and analyzing LoadGen. Non-task descriptions include operational recommendations, features of the tool, and a reference of performance counters.

      Exchange Load Generator is used as a simulation tool to measure the effect of MAPI clients on Exchange servers. LoadGen enables you to test how a server that is running Exchange responds to e-mail loads. To simulate the delivery of these messaging requests, you run Exchange Load Generator tests on client computers. These tests send multiple messaging requests to the Exchange server, which causes a mail load. LoadGen is useful for administrators who are sizing servers and validating a deployment plan. Specifically, LoadGen helps determine whether each of your servers can handle the load that they are intended to carry. Another use for LoadGen is to help validate the overall solution.

      The Exchange Load Generator and the accompanying documentation replace the Load Simulator tool and information.
