TSQL to get a quick information on detailed distribution of memory allocated
By design the components that are aware of the SQL Server memory management mechanisms use the buffer pool for small memory allocations. If the allocation is bigger than 8 KB, these components use memory outside of the buffer pool through the multi-page allocator interface.
select
type, sum(multi_pages_kb)
from
sys.dm_os_memory_clerks
where
multi_pages_kb != 0
group by type
More detailed information about memory allocation by the server components can be assessed by using the sys.dm_os_memory_clerks DMV.
