Report Taking A Long Time

Question

I have a report, that if I hard code the parameters, then it takes 5 seconds to return data.
If I use a bind variable (page item), see below, then it takes 25 seconds to return data.
select * from (
select A.ITEM_ID, 
A.VIN,
B.MAKES,
C.MODEL,
A.BFG_NO,
A.FRG_NO,
H.PERSONAL_NO,
H.SURNAME,
A.NON_BFG_REG_NO
from MER_VEHICLE_OWNERSHIPS G,
MER_IMPORTED_ITEMS A, 
MER_PERSONS H,
MER_MODELS C,
MER_MAKES B
WHERE B.MAKE_ID(+) = A.MAKE_ID
AND C.MODEL_ID(+) = A.MODEL_ID
AND G.ITEM_ID = A.ITEM_ID
AND H.PERSONAL_ID = G.PERSONAL_ID
AND NVL(H.SECURITY_ID, 2) != 1
AND G.VALID_FROM = (SELECT MAX(VALID_FROM)
                      FROM MER_VEHICLE_OWNERSHIPS
                       WHERE ITEM_ID = A.ITEM_ID) 
where (
instr(upper("VIN"),upper(nvl(:P300_SEARCH,"VIN"))) > 0 or
instr(upper("MAKES"),upper(nvl(:P300_SEARCH,"MAKES"))) > 0  or
instr(upper("MODEL"),upper(nvl(:P300_SEARCH,"MODEL"))) > 0  or
instr(upper("BFG_NO"),upper(nvl(:P300_SEARCH,"BFG_NO"))) > 0  or
instr(upper("FRG_NO"),upper(nvl(:P300_SEARCH,"FRG_NO"))) > 0  or
instr(upper("NON_BFG_REG_NO"),upper(nvl(:P300_SEARCH,"NON_BFG_REG_NO"))) > 0
)Can anyone explain why ? and how I can speed it up

I have the below code on one of the reports and it takes for ever to load the page. In Prod tier the page never returns as we have excess data. Is there a way to resolve this issue ?
select
OBJECTID,
RSDA_ID,
COUNTY,
RESIDENCY_CODE,
JURIS,
FULLSTNAME,
HWY_NUM,
LENGTH_MILES,
CAUSE_OF_RESTRICTION,
ROAD_STATUS,
REPLACE(SHIELD,' ','') SHIELD,
COMMENTS,
FC,
UPLOAD_DATE_TIME
from   GISLINK.V_ROAD_STATUS_CURRENT
Where (  :P100_COUNTY_FILTER = 'EVERYTHING'
      OR :P100_COUNTY_FILTER = COUNTY)
and
(  :P100_RESIDENCY_FILTER = 'EVERYTHING'
      OR :P100_RESIDENCY_FILTER = RESIDENCY_CODE)
and
(  :P100_FC_FILTER = 'EVERYTHING'
      OR :P100_FC_FILTER = FC)
and
to_char(ROAD_STATUS) = to_char(decode(:P100_ROAD_STATUS_FILTER,'EVERYTHING',ROAD_STATUS,:P100_ROAD_STATUS_FILTER))
and
to_char(CAUSE_OF_RESTRICTION) = to_char(decode(:P100_CAUSE_FILTER,'EVERYTHING',CAUSE_OF_RESTRICTION,:P100_CAUSE_FILTER))Edited by: Lucy Discover on Sep 6, 2011 10:56 AM
