Top Cached SPs By Avg Elapsed Time (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name], qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], qs.total_elapsed_time, qs.execution_count, ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second], qs.total_worker_time/qs.execution_count AS [AvgWorkerTime], qs.total_worker_time AS [TotalWorkerTime], qs.cached_time FROM sys.procedures AS p WITH (NOLOCK) INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK) ON p.[object_id] = qs.[object_id] WHERE qs.database_id = DB_ID() ORDER BY avg_elapsed_time DESC OPTION (RECOMPILE); [/sourcecode] – This helps you find long-running cached stored procedures that may be easy to optimize with standard query tuning techniques

Lists top statements by average input/output usage for current database
