Understanding performance bottlenecks using performance dashboard
The Performance Dashboard is a set of reports deployed using custom reports in SQL Server Management Studio that help identify common performance issues like blocking, high CPU usage, and I/O bottlenecks. It is installed from Microsoft downloads and configured by running a script on the target SQL instance. The dashboard provides information on CPU usage, blocking, waits, and index recommendations to help troubleshoot bottlenecks without executing queries directly.

- 3. What is PerformanceDashboardA set of RDLs deployed using custom reports feature in Management Studio which help resolve the most common performance issues, such as blocking, high CPU usage, latch contention and disk I/O bottleneck, without having to execute T-SQL queries.
- 4. Installation and UsageInstallthe Performance Dashboard Reports from Microsoft Downloads siteOnce you install the above, go to \Program Files\Microsoft SQL Server\90\Tools\PerformanceDashboardand run the setup.sql script against the SQL instance that you want to monitor the performance for.Right click on the Server Name in Object Explorer -> Reports -> Custom Reports and select performance_dashboard_main.rdl
- 5. What can itbe used for?CPU bottlenecks (which queries are consuming the most CPU and Plan for this query)IO bottlenecks (which queries are performing the most IO and Plan for this query).Index recommendations generated by the query optimizer (using Missing Indexes DMV feature)BlockingLatch contention and other Wait Types
