Oracle first N rows of a group using RANK running too slow - oracle

Question

I have a table with below columns
Table{
load_date DATE
effective_date DATE
Application_ID Varchar2
Datasource_id VARCHAR2
Rule_id Varchar2
Entity_Id varchar2
Rule_status number
batch_execution_ts TIMESTAMP
}
Now I have a query to fetch results as below
select * from (
select rank() over (partition by effective_date, rule_id, entity_id order by batch_execution_ts desc) as rank,
s.*
from TABLE s
where s.load_date between :date1 and :date2
and s.effective_date between :effdate1 and :effdate2
and application_id=:appid
and datasource_id=:dsid) result
where result.rank=1
We have a query requirement to send results in max od 3seconds.. but this query is running for whopping 4 mins and no results returned. TABLE is partitioned on "load_date"and we have LOCAL INDEX created on effective_date, application_id, datasource_id, rule_id, entity_id
Any suggestion on improving performance. FYI.. each load_date partition contains around 2-3 million rows. Running parallel is not helping the performance either.
