Because in the past, when someone mention performance issues, the
replies come in with:  is DB structure optimized,  are queries
optimized, is the code optimized?  For those in the field long enough
and have all that optimized and want additional performance boost,
what else are there?  Thus, when I mentioned threads/parallel, I don't
mean execution of queries, but of everything in the entire app/project
where the gain is desired.
