As we can forsee that we'll have similar insert rates to cope with in
the not-so-far future, what do you mean with 'upsert'? Do you mean a
stored procedure that iterates over the temp table?

Generally, what is the fastest way for doing bulk processing of
update-if-primary-key-matches-and-insert-otherwise operations?

Thanks,
