Top Cached SPs By Total Logical Reads (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name], qs.total_logical_reads AS [TotalLogicalReads], qs.total_logical_reads/qs.execution_count AS [AvgLogicalReads],qs.execution_count, ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second], qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], 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 qs.total_logical_reads DESC OPTION (RECOMPILE); [/sourcecode] – This helps you find the most expensive cached stored procedures from a memory perspective – You should look at this if you see signs of memory pressure
