Thanks. So, the Write-Ahead-Logging (being used or not) does not matter?

And, is there anything like RAM-only tables? I really don't care whether
the staging data is lost on the rare event of a machine crash, or
whether the query crashes due to lack of memory (I make sure there's
enough w/o paging) - I only care about performance here.
