可以使用性能计数器,
\sqlserver:plan cache(temporary tables & table variables)\cache pages
\sqlserver:plan cache(extended stored procedures)\cache pages
\sqlserver:plan cache(bound trees)\cache pages
\sqlserver:plan cache(sql plans)\cache pages
\sqlserver:plan cache(object plans)\cache pages
\sqlserver:plan cache(_total)\cache pages
也可以使用t-sql
查看服务器中存储过程和adhoc,autoparameterized prepared plan的比例,大小
select name,type,single_pages_kb, multi_pages_kb,(single_pages_kb+multi_pages_kb)/1024 as total_sizeMB, entries_count
from sys.dm_os_memory_cache_counters
where type in ('cachestore_objcp','cachestore_sqlcp')
--where type in ('cachestore_objcp','cachestore_sqlcp','cachestore_phdr','cachestore_xproc')
从下面这个图中可以看出,服务器中sp使用比例极少
select type,count(*) from sys.dm_os_memory_cache_entries
where type in ('cachestore_objcp','cachestore_sqlcp')
group by type
