Hi, we have exactly the same (partitioned) table in 2 seperate databases. Both are being pumped with data from the same load process. However, one is growing 5 times faster than the other. Why could that be considering the table creation script is the same.

maybe one table is creates with COMPRESS clause and other with NOCOMPRESS?
and other thing, maybe in one ETL scrip you use /*+ APPEND*/ hint and in other not?

Check database blocks, tablespace parameters (extent management, allocation type, segment space management), table and partition storage parameters.
Also check database versions up to 4 decimals.

do you use /*+ APPEND */ hint in etl ?
you can try to create the taple copies on all two databases
use the same table creation DML and name tables with _tmp at end.
on both databases load new tables from old ones with data using
insert into tblnm_tmp
select * from tblnm

and look at the size of the tables in tablespaces.

(or maybe you talking about row count growing 5 times faster?)
