It's easy to write "unit test" tests that use JUnit and some mocking library. They may produce code coverage that keeps some stakeholders happy, even though the tests aren't even unit tests and provide questionable value.

A performance tuning engagement can end up taking many turns as you work through it – it all depends on what is showing up as the problem and what the data tells you. Some days it lands on a specific query, or set of queries, that can be improved with indexes – either new ones or modifications to existing indexes.
