Subj:   Re: Indexes and Multiload
From:   Tressler, Dara C.


I have found that secondary indices degrade the performance of the Multiload. Therefore, we always drop secondary indices before loading and recreate/collect statistics on them afterwards. This is faster even for large tables than inserting with secondary indices on the table. I have noted around an order of magnitude slower loads when the indices are kept on the table. We are still at V2R4.1 TTU 6.2.
