I am looking at oracle supplied locking query ... any idea how to tune this ?

SELECT l.SID,s.serial#,s.username,s.terminal,

DECODE(l.TYPE,'RW','RW - Row Wait Enqueue', 'TM','TM - DML Enqueue', 'TX','TX - Trans Enqueue', 'UL','UL - User',l.TYPE||'System') res,

        SUBSTR(t.NAME,1,20) TAB,u.NAME owner,
        l.id1,l.id2,
        DECODE(l.lmode,1,'No Lock',
                2,'Row Share',
                3,'Row Exclusive',
                4,'Share',
                5,'Shr Row Excl',
                6,'Exclusive',NULL) lmode,
        DECODE(l.request,1,'No Lock',
                2,'Row Share',
                3,'Row Excl',
                4,'Share',
                5,'Shr Row Excl',
                6,'Exclusive',NULL) request

FROM v$lock l, v$session s,
sys.USER$ u,sys.obj$ t
WHERE l.SID = s.SID

AND s.TYPE != 'BACKGROUND'
AND t.obj# = l.id1
AND u.USER# = t.owner#
