Otimizar Query

Galera,

Alguem consegue me ajudar a otimizar esta query?

SELECT P.NrContrPed, C.NrContrCli, P.NrPed FROM PedSai P
Inner Join Clientes C
On C.NrContrCli = P.NrContrCli
Inner Join EndCli E
On E.NrContrCli = C.NrContrCli And E.NrSeq = ´01´ AND E.ClassifEnd = ´1´
Inner Join CtRec Ct
On Ct.NrContrPed = P.NrContrPed
WHERE ((Tel1 = ´12341234´ And DDD = ´11´) OR (Tel2 = ´12341234´ AND DDD = ´11´))
OR (Tel3 = ´12341234´ AND DDD = ´11´) OR (CdBip = ´12341234´)
