Are you performing transactional access or read queries or a mixture, and what is the makeup of the mixture.

Are the two applications the same application on a cluster or two different apps? What is the nature of the database interactions, OLTP with heavy transactional access or big queries?

What slows down? A page serving big data or a page serving OLTP or every single page, ...

Are you sure the database is the culprit? Maybe networking is getting bogged down, maybe the switching logic is the culprit
