up the registry before you edit it. If you are running the Microsoft Windows NT® or
Microsoft Windows® 2000 operating system, you should also update your emergency
repair disk (ERD).
No Performance Optimizer
The Performance Optimizer (also known as PerfWiz) is an Exchange 5.5 tool that enables
you to specify how an Exchange 5.5 computer is to be configured—for example as a
private store or a public store server. In addition, you can limit an Exchange 5.5 server’s
memory usage and specify how many users it would be expected to handle. Based on
your choices, files written by the various Exchange components (information store, message
transfer agent [MTA], and so forth) can be assigned to specific fixed disks, depending upon
available storage.
Exchange 2000 does not use a tool like Performance Optimizer. One reason for this is
that the new release of Exchange is better capable of performing certain tasks as they are
required, such as dynamically changing certain parameters, spinning up more threads, and
so on. To go beyond these dynamic changes, the administrator must manually optimize
disk utilization and manually modify registry keys, but fewer such registry changes are
necessary.
