I agree, let's first find a reproducible example where "updates"
negatively impacts large table scans ... one that is rather simple (if
there is one) to reproduce and then work from there.

I might be able to help with such an example during the month of
December/January :)

I do have a question though? (Should probably ask in database-discuss).

Q: Does a full online backup of a DB (let's say Legato Networker with
oracle plugin) constitute "large sequential table scans" in the way
that it reads database data? It probably is not as simple as that...
