Delta load performance

Hi All,

I am using delta load and full load with the conditional.

Fact table data flow is like this:

DF1: Oracle --> Staging

DF2: Staging--> DWH

I am passing Dimension table value by using lookup_ext tranform at Staging--> DWH

No of rows in Dimension table is 200

no of rows in Fact table is 125,000.

Full load is taking 3 mins where as delta load is taking 30 mins.

Please check below sample job screens.

Kindly advise to improve the performance.

Thanks in advance.

BODS Version is XI3.1
