I was talking to some colleagues and they did the following tests. I was wondering if anyone else had similiar results or maybe they just didnt do it properly.

They are using standard SQLLOADER. No direct path inserts and doing some SQL data manipulation of the files. They found the following:

SQLLOADER with the SQL manipulation is much slower than Direct Path SQLLOADER to a staging table, then insert,update, and delete to the master table.
As they increased the Array size or the commit size, the performance degradated rapidly.

This sounds odd. Anyone else notice this? Or did they just do something wrong. Dont know what they did. They tried it before I started, I just have hearsay to go on. Sorry about the lack of details.
