When you evaluate the performance of an Exchange 2000 Server computer, you may notice that the amount of virtual memory available on the server is less than you expected, which appears to affect the performance of the server. In particular, tasks for which the information store databases must be accessed may appear slower than expected.

This problem may be caused by the fact that a large amount of virtual memory is unavailable to other processes because it is being used by the information store. For example, the Exchange database engine caches portions of the information store databases in memory. If less memory is available, the Exchange database engine is unable to cache as much of the databases, which increases the amount of time required to access that information.
