Im still not sure what actual performance problem your seeing ...
It seems that most responders have expressed the same concern. It's hard to offer performance advise when details are missing. It seems that only Mark can fill in the gaps.
Several responders offered the same advise - tune performance with indexes. But wouldn't a vendor package normally come with indexes, or predefined scripts for creating the ones needed?
One problem that I've seen is the case where connections are assigned arbitrarily from one pool. Say one user activates a menu item for working with user profile data, and a pool manager assigns connections arbitrarily, so that the user profile table is eventually opened in say 10 QZDASOINIT jobs, even though the table was used by just one user. In some cases pooled connections never release their resources. Arbitrarily assigning connections from a pool and failing to release resources after an application completes is a good way to create memory leaks, and use unnecessary CPU too. But it normally only surfaces after applications and users grow to a significant number.
