Performance Issue with SQL 2012 AG & SCOM 2012

I am seeing some Perf Issue in My Ops Mgr DB implementation . I have migrated to new HW , But still the Perf issue is present.

On Closer Look , I Ran the below Query on the my Ops DB which is hosted on SQL 2012 SP1 with Always-On Enabled & found some unusual Stuff Occupying my Ops Mgr. DB

WITH xCTE([ObjectName], [PartitionId], [Rows], [Type])AS

(

    --Get the partition information for all internal tables that we are interested in

    SELECT so.name, p.partition_id, p.row_count, so.type

FROMsys.objects so

    LEFTJOINsys.dm_db_partition_stats pON p.object_id= so.object_id

    --WHERE so.name IN ('sysdercv', 'sysdesend', 'sysxmitqueue', 'sysconvgroup', 'sysremsvcbinds')

       --AND p.index_id = 1 --Only care about clustered index

    UNIONALL

    --Get the partion information for all the service queues in the db

    SELECT so.name, p.partition_id, p.rows, so.type

FROMsys.objects so

    LEFTJOINsys.objects so2ON so.object_id= so2.parent_object_id

    LEFTJOINsys.partitions pON p.object_id= so2.object_id

    WHERE so.type='SQ'    --type "SQ" = Service Queue

       --AND p.index_id = 1    --Only care about clustered index

       AND so.is_ms_shipped= 0    --Do not care about MS shipped broker queues

)

SELECT ObjectName,Type

    ,CAST((reserved_page_count* 8.0)/1024.0 ASDECIMAL(10, 2))AS'Reserved Space (mb)'

    ,CAST((used_page_count* 8.0)/1024.0 ASDECIMAL(10, 2))AS'Used Space (mb)'

    , [Rows] as'Rows'

FROM xCTE x

LEFTJOINsys.dm_db_partition_stats sON x.PartitionId = s.partition_id

ORDERBY'Reserved Space (mb)'DESC

Similarly I ran the Same Query on SQL 2008 DB , this File seem to very Less Utilized.

Does anybody have any Idea how do I work to get file Eliminated or minimize it usage in SQL 2012 for Ops Mgr. DB implementation .

Or any method which would be workaround for the above.
