Load Simulator Exchange 2000 Server Resource Kit Published: February 1, 2003 Summary The speed with which you can get work done over your network depends in part on how your server responds to mail loads. Exchange Server Load Simulator (LoadSim) is a benchmarking and deployment verification tool designed to test how a server responds to mail load. LoadSim enables you to simulate the delivery of multiple MAPI client messaging requests to a server running Exchange. After the tests are complete, you can use the results to help you to: Verify the overall deployment plan. Identify bottlenecks on the server. Validate Exchange settings and server configurations.
