How to Test on the Performance Side of Things

This is a good problem to solve very actually hard, because most of diff tools we see. Liquid base also has the diff and pyjadmin hasdiff, there are separate projects like MIGRA. Avora has thin cloning, which is in my opinion, not good for testing. It's too expensive and it's too slow. So that raises the question about test, like how do you test on the performance side of things? Is this all and how do multiple people work together, that kind of thing?
