I was presenting a new load process and I am using straight merge selects from external tables and one of the complaints that came up was that

Performance would be worse because I wasn't committing more frequently.

If my merge was too large memory swapping would occur and it was possibly related to rollback.

I said I was not aware of this and would look into it but I had never heard of this before and couldn't find any information on this so of course I'm sending mail to the list. Both items sound bogus to me. I've really never heard where committing more frequently on a load would help performance in any way.

Thanks, Dave
