Find Most Executed Stored Procedures

An important step in optimizing a system is to take a holistic approach and look at stored procedures that are called very often. These procedures can often be the backbone of a system. Sometimes optimizing these procedures can have a dramatic effect on relieving the physical bottlenecks of the system and improving end-user experience.

The following DMV query shows the execution count of each stored procedure, sorted by the most executed procedures first.

[cc lang=”sql”]
SELECT
DatabaseName = DB_NAME(st.dbid)
,SchemaName = OBJECT_SCHEMA_NAME(st.objectid,dbid)
,StoredProcedure = OBJECT_NAME(st.objectid,dbid)
,ExecutionCount = MAX(cp.usecounts)
FROM sys.dm_exec_cached_plans cp
CROSS APPLY sys.dm_exec_sql_text(cp.plan_handle) st
WHERE DB_NAME(st.dbid) IS NOT NULL
AND cp.objtype = ‘proc’
GROUP BY
cp.plan_handle
,DB_NAME(st.dbid)
,OBJECT_SCHEMA_NAME(objectid,st.dbid)
,OBJECT_NAME(objectid,st.dbid)
ORDER BY MAX(cp.usecounts) DESC
[/cc]

These execution counts are an aggregate from the last time SQL Server has been restarted.
