A Microsoft Exchange Server tool that automatically analyzes your hard disk subsystem and suggests where to locate various Exchange components such as the information store and transaction logs. Performance Optimizer also modifies certain registry settings to improve messaging performance.
Performance Optimizer runs when you finish setting up a new Exchange server. You should also run it whenever you change the configuration of a server’s core services - for example, if you change the configuration of the information store, Exchange directory service, or Message Transfer Agent (MTA), if you install or remove a connector or gateway, or if you add more RAM or another disk or processor.
