Thanks for this
Do you know of a way to check if my an instance is experiecing a plan cache bloat? What I mean is, how can I check what the allocated size of my plan cache is and how much of it has been used.
Check out the following blog by Kimberly Tripp: http://www.sqlskills.com/blogs/kimberly/post/procedure-cache-and-optimizing-for-adhoc-workloads.aspx.
SELECT objtype AS [CacheType]
, count_big(*) AS [Total Plans]
, sum(cast(size_in_bytes as decimal(18,2)))/1024/1024 AS [Total MBs]
, avg(usecounts) AS [Avg Use Count]
, sum(cast((CASE WHEN usecounts = 1 THEN size_in_bytes ELSE 0 END) as decimal(18,2)))/1024/1024 AS [Total MBs - USE Count 1]
, sum(CASE WHEN usecounts = 1 THEN 1 ELSE 0 END) AS [Total Plans - USE Count 1]
GROUP BY objtype
ORDER BY [Total MBs - USE Count 1] DESC
