This article discusses new performance counters that are included in the August 2005 update for Microsoft Exchange 2000 Server. If you experience a problem or a performance issue with information store searches, you can use these new performance counters to help you troubleshoot the problem or the performance issue.

Improved search-related performance counters have been added to Microsoft Exchange 2000 Server in this software update. The particular features that are discussed in this article do not affect the performance of the computer. The information that is provided by these counters may not be directly useful to you. However, the error reporting and the performance monitoring information may be useful to Microsoft support professionals when they troubleshoot your search-related issues in Exchange 2000 Server.

This update includes the following performance counters:

Counter	Function
Search Task Rate	The number of search tasks that are created per second
Restricted View Cache Hit Rate	The rate at which restricted views are reused in the store
Restricted View Cache Miss Rate	The rate at which restricted views are created in the store
Slow FindRow Rate	The rate at which the slower FindRow has to be used in the store
