RE: performance impact of archivelog

1. Performance cost of running in archivelog mode.

We take our database out of archive log mode for a yearly batch process. Very roughly the dry run (which is run on a different but similarly specked machine in archive log mode) takes about 20% longer.

Obviously as the difference is going to be dependent on how much change is going on, your mileage may vary.

Subject: performance impact of archivelog

Has anyone on the list seen a discussion of

1. performance cost of running in archivelog mode.
2. overhead of using partitions
3. time calculation to perform statistics
4. time savings of using statistics

I always see these things discussed in terms of "more" but never in terms of "how much".

Thanks for any information that you can point me to.
