Having one or more subsystems that are underperforming alters the responses and behaviors of a server. Usually, this means that the server becomes unresponsive or falls below what is considered acceptable operational behavior. This diminished performance puts the service level agreement (SLA) at risk, which ultimately means the organization itself can suffer.

These topics provide administrators of Microsoft® Exchange Server 2003 with information about how to isolate performance degradations and how to use existing tools and products, such as Performance, Load Simulator, Exchange Stress and Performance 2003, Network Monitor, and Filemon, for this purpose. The information in these topics can also be used to ensure that a server is not degrading over time because of hardware issues or malfunctions.

Note that it is beyond the scope of these topics to ensure that a server is healthy, or to diagnose or solve user experience problems. Although performance issues with the server generally translate to a poor user experience (such as slow client response), this is not always true and the reverse does not necessarily hold. Before concluding that a poor user experience results from a poorly performing server, it is important to correlate the user issues with observed degradations on the server.
