Sql query taking long time with inner join

Sql query taking long time with inner join

I am supposed to write a query which requires joining 3 tables. The query
designed by me works fine, but it takes a lot of time to execute.
SELECT v.LinkID, r.SourcePort, r.DestPort, r.NoOfBytes, r.StartTime ,
r.EndTime, r.Direction, r.nFlows
FROM LINK_TBL v
INNER JOIN NODEIF_TBL n
INNER JOIN RAW_TBL r ON
r.RouterIP=n.ifipaddress
and n.NodeNumber=v.orinodenumber
and v.oriIfIndex=r.OriIfIndex;
Is there any issue w.r.t performance in this query ?
